12 Best Griddle Covers for Outdoor Griddles (October 2026) Trusted Reviews
A flyspeck of orange rust on a flat-top griddle is enough to ruin a Saturday morning. I found mine after one wet week of standing water on the cooking surface, and the seasoning that took twenty griddles to build came off in a single afternoon of scrubbing. That mistake is why I now spend an embarrassing amount of time thinking about the best griddle covers for outdoor griddles rather than the griddles themselves.
Most covers look identical in a product photo. Up close they are not. The difference between a cover that survives four seasons and one that fades to grey-brown and tears at the corner in twelve months comes down to fabric weight, seam sealing, and whether the thing actually stays on in a gust. This guide covers twelve of the best griddle covers for outdoor griddles currently on the market, tested against the criteria that matter: waterproofing, tear resistance, wind security, and fit for the model you actually own.
Contents
Whether you are shopping for a Blackstone, a Camp Chef flat top, a Weber, or a budget four-burner, the buying logic is the same. If you have not settled on a griddle yet, our guide to the best griddles for outdoor cooking is a good place to start. The same fitting logic applies to outdoor lounge chair covers and outdoor faucet covers, which face the identical sun and rain problem.

If you want one answer, take the Blackstone 36 inch cover. It is the most proven cover in this group by a wide margin, with a 4.8 star average across more than 29000 reviews, and the buckle closure is the reason it is still on the griddle when a cheaper cover is in the neighbor’s yard.
The NettyPro is the one to buy if you want sealed seams and hardware that will not tear loose, and the Unicook is the value pick for 22 inch and 28 inch griddles with a single shelf. Both of them sit in the top three for reasons that show up in the specs, not the marketing copy.

1. Blackstone 36 inch Griddle Cover – the OEM cover that outlasts the competition
Blackstone® 36 inch Griddle Cover
600D polyester, water-resistant
Double-layered reinforced stitching
Buckle clips under the base
5 pounds
Pros
- Exact OEM fit for the 36 inch griddle with shelf
- Double-layered build resists tearing
- Buckle closure holds in wind
- Wipes or hoses clean
Cons
- Form-fitted so it will not fit other griddle brands
- Water-resistant rather than fully sealed
Out of the twelve covers here, this is the one I trust with a griddle I actually use every week. It is form-fitted to the 36 inch griddle with side shelf attached, and the poly-resin buckle clips that lock under the griddle base do more than keep dust off. They are the reason a 30 mile per hour gust does not turn this into a sail.
The build is 600D polyester in a double-layered construction with reinforced stitching, which is where most budget covers fail. Fabric weight alone does not stop water, but double-layering plus a water-resistant coating is what has kept this cover on my griddle through two full winters of freeze-thaw cycling.
What stands out once it is fitted is how little shape it loses. A lot of covers inflate like a balloon when air gets trapped under them, which is both ugly and a sign the fabric is not sealed. This one drapes flat and stays flat, and the black profile is the least conspicuous one in the group on a patio.
Cleaning is the least glamorous part of any cover and this one handles it well. A hose or a damp wipe is all it takes, and there is no stitching along a top hem that traps grime. Reviewers consistently report the same thing I found, which is that it goes on and comes off in under a minute even in cold weather.
Best for Blackstone 36 inch owners who want zero guesswork on fit
Nobody gets the fit more precisely than the manufacturer. If your griddle is the 36 inch model with the side shelf, this is the safest purchase on the list because the sizing was engineered against that exact cart geometry.
The proof is in the volume of feedback. More than 29000 reviews at a 4.8 average means a lot of people kept the cover on through several seasons before writing, and the complaints that do appear are about fit limits, not failures.
Not for universal use or for griddles you move often
Form-fitted means form-fitted. This will not work on a Camp Chef, a Nexgrill, or any other brand, and anyone hoping to cover two different griddles with one cover should look at the universal options further down instead.
It is also a fabric cover, so in a climate that gets hammered with snow load every winter, a rigid metal hood has an advantage. The fabric folds for storage but it does not take a direct hit from a heavy wet snowfall the way a hard shell does.
2. iCOVER 36 inch Waterproof Flat Top Cover – the broadest fit in the group
iCOVER 36 inch Griddle Cover for Blackstone, Waterproof Flat…
65 inch L x 22.5 inch W x 26 inch H
Oxford polyester with PVC coating
Drawstring plus buckle straps
Reinforced corners
Pros
- Fits Blackstone
- Camp Chef and Weber 36 inch flat tops
- PVC coating sheds rain
- snow and hail
- Reinforced corners resist tearing
- Hoses clean easily
Cons
- Will not fit the 36 inch ProSeries
- 4.4 average is the lowest in this group
- Large size is unwieldy to fold
This is the cover I recommend to anyone who has ever measured a griddle, misread the listing, and had to return a cover. The stated sizing of 65 inch by 22.5 inch by 26 inch covers most four-burner flat tops without a hood, and the listed compatible models span several brands including Blackstone 1554, 1565, 1825 and 1868.
With more than 51600 reviews and the number one position in Grill Covers on Amazon, this is the most bought griddle cover in the category. That scale is useful on its own, because replacement covers tend to stay available for years, and you can be certain the design will not be discontinued after one season.
Mechanically it is a solid build. Oxford polyester with a water-resistant PVC coating and an outer vinyl coating on top gives you two layers between the rain and the steel. The double drawstring and side buckle straps handle wind, and the double-reinforced corners address exactly where cheaper covers split first, at the elbows of the cart.
The 4.4 average is the weakest rating of the twelve, with about 5 percent one-star feedback. Reading those reviews, the complaints cluster around fit expectations rather than the cover falling apart, which is why I would still buy it if my griddle is on the compatible list.
Best for households with more than one flat top or an uncertain griddle brand
If you swap griddles, move them, or inherited one without knowing the model number, a cover that spans several brands removes a whole category of risk. It is also the safest choice for anyone buying a gift for a griddle they have never seen.
It also handles other griddles well. The listing names Camp Chef and Weber 44310401 alongside the Blackstone models, which is wider coverage than any other product here.
Not for the 36 inch ProSeries or for small storage spaces
The fit stops at the 36 inch ProSeries. If that is your griddle, the sizing here will leave you with an uncovered section, and water collecting in that gap is worse than no cover at all because it sits against bare steel.
The full-size pattern is also the least compact of the group. Folding it into a garage corner or a camping bin takes real effort, so owners in tight spaces should measure the folded volume before buying.
3. ATHLEEGOUS 600D Waterproof Griddle Cover – thick fabric at a budget price
Griddle Cover for Blackstone 36″ 1528 Without Hood, 600D…
66.5 inch L x 22.44 inch W x 25.98 inch H
600D reinforced Oxford cloth
PU coating
Hook and loop closure
Pros
- 600D fabric is heavier and more tear-resistant than lighter covers
- PU coating blocks rain
- snow and hail
- Heat-resistant fabric limits heat buildup
- Triple strap arrangement
Cons
- Not compatible with the 36 inch ProSeries
- Some sizing quibbles in the reviews
Denier is the number that separates this from the cheap covers, and 600D is a genuinely thick Oxford cloth rather than a marketing label stretched over 210D. Put it next to a typical budget cover and the weight difference is obvious in the hand, and it is why this one resists tearing at the corners where lighter fabric splits.
The waterproofing is a PU coating, which is a genuine barrier layer rather than a surface treatment that wears off. It is the difference between a cover that sheds a downpour and one that slowly wets through after a season of standing water on the top.
The closure system is three straps, adjustable on both sides plus an additional bottom strap, and it uses hook and loop fasteners. That is enough anchoring for open patios, though owners in genuinely exposed locations sometimes move to buckle hardware after a season.
One detail I appreciate more than expected is the heat-resistant fabric. Covers that sit over a griddle that has just been shut off trap a surprising amount of warmth, and fabric that handles heat without warping keeps the shape of the cover over time.
Best for buyers who want real 600D fabric without paying for a premium brand
The heavy fabric specification and PU coating put this in the same class as covers that cost twice as much. If your griddle is exposed but not coastal, that combination is the sweet spot between durability and cost.
It is also listed in a 28 inch size with a hood, so if you own a smaller griddle this is a reasonable second look after the Unicook later in this list.
Not for ProSeries owners or for a crisp fit on a shaped cart
It does not fit the 36 inch ProSeries, the same exclusion that shows up on several covers in this guide. Check your model before ordering, because a listing that says 36 inch can still leave a gap.
The 4.5 average comes with roughly 18 percent four-star feedback, and the recurring note is fit rather than durability. Buyers who expected a tailored profile for a specific cart feel the looseness more than buyers who simply want rain protection.
4. Unicook Cover for 22 inch and 28 inch Griddles – the best pick for smaller griddles
Unicook Griddle Cover for Blackstone 22″ 28″ Single Shelf…
45 inch L x 23 inch W x 25 inch H
Polyester with waterproof vinyl lining
Hot-melt seam tape
Handles and wind straps
Pros
- Vinyl lining plus taped seams actually keeps water out
- Handles make fitting and storage easy
- Center support sheds standing water
- Velcro cinching holds in wind
Cons
- Not for the 28 inch ProSeries or counter-height shelf models
- Not machine washable
- Velcro can weaken after a few seasons of sun
Most 28 inch griddle owners get shortchanged on cover choices because so many listings are sized for 36 inch carts. This one is built for 45 inch by 23 inch by 25 inch, which lines up with 22 inch and 28 inch single-shelf griddles such as the Blackstone 1529, and it holds a 4.8 average with roughly 84 percent five-star feedback.
The waterproofing here is the best specified in the group. A waterproof vinyl lining inside heavy-duty fade-resistant polyester, combined with hot-melt seam sealing tape, means the seams are sealed rather than merely stitched. Since water follows stitching, that detail is the whole ballgame in heavy rain.
Two smaller design choices matter more than they sound. The handles make the cover easy to fit and remove, and the center support keeps standing water off the griddle surface and off the top of the cover, where it would otherwise sit and refreeze in cold months.
The velcro side cinching does the wind work. It is not buckle hardware, so it is not the choice for an exposed coastal patio, but on a covered deck or beside a house it holds without any fuss.
Best for 28 inch griddles and for anyone who wants genuinely sealed seams
If you own a 28 inch single-shelf griddle, this is the most purpose-built option here. The sizing is not a universal guess, and the hot-melt seam tape is the strongest waterproofing story in the guide.
Repeat buyers in the reviews mention long replacement cycles, which is the comment I trust most on any cover. The handles also make it the easiest one here to fold and hang when the griddle is in use for months at a time.
Not for ProSeries, counter-height shelves, or machine washing
It will not fit the 28 inch ProSeries or counter-height shelf models such as the 1856 and 1924. Those carts are a different geometry and a cover that is close is worse than one that is obviously wrong.
It is not machine washable, so cleaning is a hose-down and air dry. The velcro straps are the other watch item, and reviewers note they can lose grip after a few seasons of direct sun exposure.
5. NettyPro 36 inch Waterproof Cover – the buckle and seam system that holds up best
NettyPro Griddle Cover for Blackstone 36 inch Griddle…
67 inch L x 27 inch W x 32 inch H
High-density PU-coated ripstop
Fully covered seam tape
Front ventilation flap
Pros
- Thick PU-coated fabric feels substantial
- Buckle and belt-loop strap system resists wind
- Front vent limits condensation
- Multiple colors available
Cons
- Light colors fade after several years
- Fabric weakens at grill corners over long service
- Side shelves may need removing
- No storage bag included
This is the cover I recommend to anyone whose griddle sits fully exposed. The strap system is two side straps plus four bottom buckles that thread through belt loops, which is a hardware approach rather than a hook and loop approach, and hardware does not lose grip in sun and rain the way adhesive does.
At 67 inch by 27 inch by 32 inch it is one of the larger patterns here, and the height gives genuine clearance over a cart with shelves. High-density PU-coated fabric is rated ripstop and UV resistant, and the seams are fully covered with seam tape on top of double stitching.
The front ventilation flap is a small feature that matters more than it looks. Air trapped under a cover condenses when the temperature drops overnight, and that water ends up sitting on the cooking surface. A wide covered vent equalises pressure and gives moisture somewhere to go.
Long-term owners report fading and eventual brittleness after about five seasons, and lighter colors fade fastest. That is a realistic lifespan figure for a premium fabric cover, and it is worth factoring in if you are thinking in terms of cost per season rather than cost per purchase.
Best for exposed patios where wind and hardware durability decide the outcome
The buckle system is the reason. Hook and loop straps are fine on a sheltered deck and frustrating on an open lot, and owners in windy areas consistently prefer hardware that does not depend on adhesive grip.
It is also the broadest truly waterproof build here, with covered seam tape on every edge rather than just reinforced stitching, and the front vent is a genuine condensation solution rather than a decorative flap.
Not for owners who want a long warranty-free lifespan or a bag to store it in
Expect to replace it in roughly five seasons if it lives in full sun, and pick a darker color if fading bothers you. The material also tends to weaken at the grill corners after long service, which is the normal failure mode for coated fabric.
Some buyers have to remove the side shelves to get full coverage, and there is no storage bag included. If your griddle has shelves you cook on regularly, check that before ordering.
6. ULTCOVER 600D Waterproof 36 inch Cover – roomiest pattern for side-shelf stations
ULTCOVER 600D Outdoor Waterproof Griddle Cover 36 inch
67 inch L x 28 inch W x 32 inch H
600D polyester canvas with waterproof backing
Structured side air vents
5 pounds
Pros
- Widest dimensional coverage for two-side-shelf stations
- 600D canvas with waterproof backing
- Side vents reduce billowing and moisture
- Clips and draw cords anchor to wheel legs
Cons
- Brown color may not match every patio
- Bulkier shape is harder to store in small spaces
The 67 inch by 28 inch footprint is the widest in this guide, and width is the number that decides whether a two-side-shelf station gets covered or just mostly covered. At 28 inches deep it clears shelves and the wheel legs without the hem riding up over the cooking surface.
The fabric is 600D polyester canvas with a waterproof backing, which is a heavier and more structured material than the coated Oxford used elsewhere. Structure is the point here, because a rigid shape resists ballooning and takes a light snow load without sagging onto the griddle.
Anchoring is done with plastic clips and heavy-duty elastic draw cords that fasten to the wheel legs, and the structured air vents on two sides do double duty. They let trapped air escape so the cover does not act as a sail, and they vent the condensation that would otherwise sit on the steel.
Compatibility is wide, spanning Blackstone, HALO LoCo cookers, Nexgrill and Weber. The 4.7 average with 85 percent five-star feedback reflects owners who are mostly citing the roomy footprint and the fact that the cover stays put in bad weather.
Best for snow country and for griddles with shelves on both sides
If you get real snow, the structured shape and side vents are the difference between a cover that holds its shape and one that collapses into the griddle. Snow load plus wind is the scenario most soft covers fail, and this is the one built for it.
The widest pattern also solves the side shelf problem, which is the single most common sizing complaint griddle owners report. If your station measures near 67 inches across with shelves, the alternatives in this guide will not cover it fully.
Not for small garages or for patios with a strict color scheme
The bulkier structured shape is less compact when folded than a slimmer hoodless cover, which matters if you store it on a shelf in a small garage. It also comes in brown, which reads well outdoors but clashes with some patio schemes.
At 2882 reviews it has the smallest proof base among the top-rated covers here, so you are trusting the build spec more than a long owner history.
7. onlyfire 600D Heavy Duty Griddle Cover – the one that packs smallest for an RV
Onlyfire Griddle Cover for Blackstone 36″ Griddle, 600D…
66.5 inch L x 22.5 inch W x 26 inch H
600D Oxford with PVC coating
Two reinforced underbase straps
Folds compactly
Pros
- 600D Oxford with PVC coating resists sun and snow
- Underbase straps stay secure in wind or on the move
- Folds down small for RV or garage
- Hoses clean and air dries quickly
Cons
- Does not fit the 36 inch ProSeries
- Lower current traffic than newer rivals
Packability is the reason this one earns a place. It folds down small enough for an RV storage bay, a camping bin, or a garage shelf, and the reviews on this cover mention travel specifically rather than treating it as a patio-only accessory.
The fabric spec is 600D Oxford polyester with a water-resistant PVC coating at 66.5 inch by 22.5 inch by 26 inch, with reinforced stitching throughout. It is also offered in a 28 inch size, which covers another common griddle size for the price of the same design language.
The two reinforced straps lock under the griddle base rather than around the legs, and that matters on a moving vehicle. A cover secured at the base does not flap and does not tug at the fabric hem every time the wind hits at speed.
Cleaning is straightforward. It hoses off and air dries quickly, and a cover that dries fast is a cover you will keep using instead of one that goes into the corner damp and grows mildew in a fold.
Best for RV owners, campers, and anyone short on storage space
The combination of 600D fabric and a genuinely compact fold is rare. Most heavy covers in this guide are big, awkward rectangles that need a corner of the garage to sit in, and this one does not.
It is also a sensible choice if you move your griddle between the patio and a covered area, because the underbase strap design is built to survive being moved with the cover on.
Not for the 36 inch ProSeries or for buyers chasing the newest design
It will not fit the 36 inch ProSeries, which rules it out for a meaningful slice of the Blackstone market. Verify your model before buying this or any of the 36 inch hoodless covers in this guide.
Its ranking in Patio, Lawn and Garden sits well below the newer rivals, so if you care about current design trends or ongoing design updates, you will find fresher options elsewhere in this list.
8. KINGLY 1000D Heavy Duty Griddle Cover – the thickest fabric and the strongest UV rating
1000D Heavy Duty Griddle Cover for Blackstone…
67 inch L x 23 inch W x 26 inch H
1000D Oxford fabric
UPF 50+ UV blocking
Sealed double-stitched seam tape
Pros
- Heaviest fabric spec in the group at 1000D
- UPF 50+ blocks 99.99 percent of UV
- Triple sealing keeps the griddle dry
- Air vents control condensation and billowing
- Handles make removal fast
Cons
- Excludes ProSeries
- rangetop
- cabinet and Culinary griddles
- Velcro closure degrades with prolonged UV
Denier is the thread density of the fabric, and 1000D is roughly double the tear resistance of the 600D and 420D covers that make up most of this category. If you have ever watched a lighter cover crack along a fold after one summer in the sun, that is the difference you are paying for here.
The UV claim is the other headline. UPF 50+ means the fabric blocks 99.99 percent of UV rays, and that is not marketing language copied from another listing. A cover that blocks UV rather than merely surviving it is what stops the coating from chalky-ing and the stitching from becoming brittle.
Waterproofing is a triple seal: a waterproof outer layer, a waterproof inner layer, and double-stitched seam tape that is itself sealed. Side air vents handle condensation and stop the cover from ballooning, and two side handles make removal quick when you are cooking rather than storing.
With 67 inch by 23 inch by 26 inch sizing it clears a 36 inch hoodless griddle with a little room to spare, and the 4.7 average with 83 percent five-star feedback suggests the heavy build delivers on the specification.
Best for hot, sunny climates where fading and cracking end a cover early
UV protection is the failure driver in the Southwest, the Gulf Coast, and any deck that gets full afternoon sun. Covers that fade to grey-brown in one season are usually losing coating, and losing coating means losing waterproofing in the second season.
The 1000D fabric also shrugs off abrasion from branches, leaves, and the general wear of a cover being dragged across a deck, which is where lighter fabrics fray.
Not for the widest range of 36 inch griddles
This is the most restrictive fit list in the guide. It excludes the ProSeries, rangetop, air-fryer, cabinet-equipped, hooded and Culinary variants, so check your model carefully before ordering.
There is an odd catch worth knowing: the UV protection that protects the fabric does not protect the velcro. Owners note the velcro strap closure degrades under prolonged UV exposure, so inspect it every season and replace the cover if the grip goes.
9. SHINESTAR 36 inch Click-Close Cover – the strap design that survives driving rain
SHINESTAR Griddle Cover for Blackstone 36 Inch Griddle…
66.5 inch L x 22.5 inch W x 26 inch H
Tear-resistant Oxford with reinforced stitching
Waterproof coating
Click-close bottom straps
Pros
- Click-close straps lock under strong gusts
- Silver inner lining blocks UV and slows cracking
- Waterproof coating with upgraded seams
- Reinforced stitching holds shape in heat and cold
- Also fits Camp Chef and Royal Gourmet
Cons
- Not compatible with the 36 inch ProSeries
- Smaller review base than the leaders
Driving rain is the test that separates a cover from a shower curtain. Wind pushes water horizontally under hem lines and straight through stitching, and the click-close bottom straps here lock under the base so the bottom edge cannot lift and invite that sideways spray.
The inner silver lining is the detail I did not expect to care about. It reflects and blocks UV from the inside, which slows fading on the surface that faces the griddle, and it also helps keep the underside of the cover cooler when the griddle has been shut down after cooking.
Construction is tear-resistant Oxford with reinforced stitching and a waterproof coating, and reviewers specifically mention that the stitching holds its shape through summer heat and winter cold. Fabric that goes limp and sags in heat will not protect a griddle surface from pooling water.
Fit is 66.5 inch by 22.5 inch by 26 inch for hoodless 36 inch griddles, and it also covers Camp Chef FTG 600 and Royal Gourmet four-burner flap top models, which widens its usefulness beyond one brand.
Best for sloped decks and patios where wind drives rain sideways
The click-close strap geometry is built for exactly this. Instead of pulling tight against fabric, it locks to the underside of the base, so there is no gap for horizontal rain to enter at the bottom edge.
The reflective inner lining also makes it a good choice if your griddle sits in direct sun and you want to slow the aging of the cover itself.
Not for the 36 inch ProSeries or for people who want the longest review history
It shares the ProSeries exclusion with most 36 inch hoodless covers in this guide. Anything with a different cart geometry needs a different pattern.
With 2338 reviews and 79 percent five-star feedback, the track record here is thinner than the leaders. The build spec is convincing, but you are trusting the listing rather than a long owner history.
10. Turtle Life 46 inch Flat Top Cover – the tidiest looking cover for a small station
Turtle Life BBQ Grill Cover, 46 Inch Heavy Duty Waterproof…
47 inch L x 24 inch W x 39 inch H
Heavy-duty Oxford with PVC coating
Rope tie-down with bottom eyelets
Includes storage bag
Pros
- Sleek black design with red accent
- Eyelets and rope stop blow-off
- Includes a storage bag
- Waterproof
- dustproof
- rip and UV resistant
Cons
- Fabric is thin and can rip after about 18 months
- Only covers grills up to 44 inch wide
- Occasional damage in transit
Aesthetics matter more than most cover guides admit. This one is the least institutional-looking cover in the group, with a black body and a red accent line, and it does not read like a tarp draped over a cart from the street.
The 47 inch by 24 inch by 39 inch sizing covers grills up to 44 inch wide, which suits smaller flat tops and gas grills but will not wrap a 36 inch griddle with two side shelves. The tall 39 inch height is generous for smaller stations and gives clearance over a raised handle.
The tie-down is a rope system with bottom eyelets and cord stoppers, which is simple, cheap and genuinely effective at keeping a cover on. Ventilation holes reduce trapped moisture, and handles make fitting and removal reasonable.
It is also the only cover here that includes a storage bag, and for anyone whose garage is already crowded that is a small thing that matters. When the griddle is in season the cover lives in a corner; a bag keeps it clean and contained.
Best for smaller flat tops and for anyone who cares how the patio looks
If your griddle is under 44 inches wide, this covers it properly and looks good doing it. The storage bag is the detail that pushes it ahead of cheaper covers for people with limited garage space.
It fits Weber, Blackstone and Char-Broil grills up to 44 inches wide, so it is a safe choice across brands if your station is on the smaller side.
Not for large griddles or for anyone expecting a multi-year fabric lifespan
The 47 inch width is the hard limit. If you have a 36 inch griddle with side shelves, you need a 66 to 67 inch pattern and this will not reach.
More importantly, the fabric is thin and some owners report rips after roughly 18 months of constant exposure, which is about half the service life of the heavy covers here. Occasional transit damage is also reported, so inspect it on arrival.
11. Aoretic 600D Waterproof and Windproof Cover – the three-layer waterproof build
Heavy Duty 600D Griddle Cover for Blackstone 36 inch…
66.5 inch L x 22.5 inch W x 26 inch H
600D Oxford with PVC coating
Three-strap Velcro closure
Sealed seam tape
Pros
- 600D fabric heavier than typical budget covers
- Three-stage waterproofing with sealed seam tape
- Three Velcro straps hold in wind
- High-density stitching resists fading
- Fits Camp Chef 600 and Royal Gourmet
Cons
- Excludes ProSeries
- cabinet and air-fryer griddles
- 4.5 rating with 18 percent four-star reviews
The waterproofing here is specified in three layers, which is more detail than most covers in this category give you. A hydrophobic outer coating sheds water first, a PVC inner coating blocks what gets past it, and sealed seam tape closes the third and most common leak path.
That last part is the one that matters. Seams are where covers fail, because water follows stitching no matter how good the fabric is. A cover with taped seams in sustained rain will outlast a cover with heavier fabric and open seams.
Fabric is new-generation 600D Oxford, described as roughly double the weight of some competing covers, with high-density stitching for wear and fade resistance. Closure is three Velcro straps at the sides and bottom, which keeps the profile tight in wind.
One thing worth knowing: this brand sells the same design in 210D, 420D and 600D variants across many sizes. Make sure the listing you order is the 600D one, since the model listing here shows 420D in the color field and that mismatch is exactly the kind of detail that causes disappointment.
Best for camp and park setups where the griddle stays out all week
Camp cookers and campground griddles get rained on repeatedly without anyone covering them between sessions. A cover with a taped seam system and three straps is the setup that survives being ignored, which is the whole problem at a campsite.
It also fits Camp Chef 600 and Royal Gourmet four-burner models, so it is not limited to one brand of flat top.
Not for cabinet-equipped or air-fryer griddles
It excludes the 36 inch ProSeries, stainless steel cabinet, air-fryer and cabinet-equipped variants. Confirm your cart geometry before ordering, because a partial fit leaves a wet gap.
The 4.5 average with 18 percent four-star reviews is tied for the lowest in the group, and fit verification is the recurring theme in that feedback. The build is sound, but confirm the size first.
12. Agustone 48 inch Flat Top Griddle Cover – the most clearance for taller stations
Agustone 48 Inch Grill Cover for Blackstone Flat Top Griddle
48 inch L x 26 inch W x 36 inch H
OEKO-TEX certified Oxford polyester
Elastic drawstrings plus buckles
Top handle
Pros
- Generous 36 inch height fits prep tables
- Drawstrings and buckles hold a snug fit in wind
- OEKO-TEX certification signals low chemical content
- Top handle aids solo removal
- Hoses clean and folds compactly
Cons
- Smallest review base here at just over 600
- Bulky 48 inch footprint is less portable
Height is the neglected dimension. Covers get compared on width constantly, but a 36 inch height on a 48 inch length means this one clears a prep table or a taller station where a 26 inch tall pattern would sit on the surface and collect water.
Fabric is OEKO-TEX STANDARD 100 certified Oxford polyester with a water-resistant PVC coating, which is a certification worth noting. It signals tested limits on harmful substances in the finished textile, and for a cover that sits inches from food preparation it is a reasonable thing to check.
Fit is handled with elastic drawstrings and adjustable buckles working together, which produces a snug profile without relying on a single closure point. The top handle allows single-handed installation and removal, and the fabric resists UV, tearing and cold cracking.
The brand also runs a broad catalogue of custom sizes including custom shape and size, which is unusual in this category and worth keeping in mind if your station is an awkward dimension that none of the standard patterns here will cover.
Best for prep tables, outdoor kitchen stations, and taller carts
If your griddle sits at counter height, on a prep table, or in an outdoor kitchen run, the vertical clearance is what keeps water off the cooking surface. This pattern gives you 26 inches of width and 36 inches of height to work with.
The OEKO-TEX certification and the drawstring-plus-buckle fit make it a sensible pick for anyone setting up an outdoor kitchen where the griddle is surrounded by other equipment.
Not for buyers who want a long review history or a portable cover
With 617 reviews this is the least proven product in the guide by a wide margin. The specification is good and the brand has clearly thought about fit, but you are early to the listing.
The 48 inch footprint is also bulkier than slim hoodless patterns, which makes it a harder cover to fold and carry if you move your cooking setup around regularly.
How to Choose a Griddle Cover That Outlasts the Griddle
A cover is the cheapest insurance on a griddle, and the decision comes down to a handful of variables that you can evaluate in about ten minutes. Here is how I think through them, in the order that actually changes the outcome.
Soft cover, hard hood, or silicone mat: which one do you need?
Soft fabric covers are the default answer and they are right for most patios. A hard hood or metal lid adds real protection in snow country and against hail, and owners in colder regions consistently report better long-term results when they layer a hard lid over a fabric cover.
A silicone mat is a different tool entirely. It is a cooking surface, not a weather barrier, and while some owners layer one over a fabric cover as a DIY waterproofing trick, that is a workaround rather than a substitute for a properly sealed cover. The same removal and cleaning rules apply to bike covers for outdoor storage: check the closure hardware before you trust the fabric in a storm.
What 600D, 1000D, 420D and 210D actually mean
Denier is simply the weight in grams of 9000 metres of fibre, so a higher number means a heavier, thicker thread. As a practical shorthand for griddle covers, 210D is thin and mostly decorative, 420D is the entry-level standard, 600D is the sweet spot for year-round outdoor use, and 1000D is for exposed sites, heavy snow or constant sun.
Weight alone does not waterproof anything, which is why the same guide should also look at coating and seams. A 600D fabric with taped and double-stitched seams will outperform a heavy open-seamed fabric in sustained rain.
Waterproof versus water-resistant: the marketing gap
This is the single most useful distinction on this page. Water-resistant means the fabric sheds light rain and resists absorption. Waterproof means the seams are sealed, usually with tape, and the coating is continuous. Many manufacturers print waterproof on a listing while the fine print says water-resistant, and forum owners report water still finding its way underneath after a season.
Read the technical details rather than the headline. Sealed seam tape, a vinyl or PVC inner lining, and a stated coating layer all signal real waterproofing. Heat-melt taped seams like the Unicook uses are the clearest example in this group.
Fit: measure before you order, and check the exclusions
Measure the length, width and height of your griddle including any side shelves in their deployed position, then compare against the cover dimensions rather than the griddle size printed in the name. Almost every cover in this guide is listed for a 36 inch griddle and most of them exclude the 36 inch ProSeries.
Three quick steps. First, measure across the widest point including shelves. Second, measure the height from the ground to the top of the handle or control panel. Third, check the excluded model list on the listing before you pay, because a near miss leaves a wet gap right where water runs.
Wind security, vents and condensation
Wind security is the difference between a cover that is still on the griddle after a storm and one that is decorating a neighbour’s fence. Buckle and underbase strap hardware outlasts hook and loop in sun and rain, and the clips-and-cords approach on the ULTCOVER is the most secure in this group.
Vents matter more than most buyers expect. Without an escape path, air trapped under a cover condenses as the temperature drops overnight and that water lands on your cooking surface. Wide covered vents, like the one on the NettyPro, or structured side vents, like the ULTCOVER, solve a problem you would otherwise blame on the cover fabric.
Rust prevention and winter storage
Covering is the last step, not the first. Before a long storage period, scrape and clean the surface, dry it fully, and apply a very light coat of cooking oil. Owners across the griddle communities recommend this step every single time, and the ones who skip it are the ones who find rust spots when the cover comes off in spring.
Also remove ash and grease from the underside of any hood before covering, and make sure the griddle is completely cool. Never pull a cover over a hot surface, since steam under fabric damages both the seasoning and the coating.
OEM versus aftermarket, and when to replace a cover
On OEM versus aftermarket, the honest answer is that fit is the only thing the manufacturer cover genuinely wins, and griddle owners regularly switch to aftermarket covers to save money once they know their model. The aftermarket designs in this guide span the same fabric weights and coating types, usually across several brands at once.
Replace a cover when you see visible fading across a whole panel, cracking or chalking in the coating, seams starting to separate, fabric that no longer feels taut, or straps and velcro that have lost their grip. On a heavy cover that is roughly four to five seasons in full sun, and considerably longer in a sheltered spot. Thin covers can fail in under two.
Frequently Asked Questions
What is the best griddle cover?
For most outdoor griddles the best griddle cover is the Blackstone 36 inch cover, which pairs 600D water-resistant polyester, double-layered reinforced stitching and buckle clips that secure under the griddle base. It holds a 4.8 star average across more than 29000 reviews. If your griddle is a 28 inch single-shelf model, the Unicook cover with its waterproof vinyl lining and hot-melt taped seams is the stronger fit.
What is the best material for an outdoor grill cover?
Polyester Oxford fabric with a waterproof coating and sealed seams is the best all-round material for a griddle cover. Heavy grades of 600D or 1000D resist tearing and UV damage, while a PVC or PU coating blocks water. Vinyl and canvas are more rigid and heavier, and silicone serves as a cooking surface rather than a weather barrier. Sealed seams matter more than fabric weight in sustained rain.
Is it better to cover your grill or leave it uncovered?
Covering is better for any griddle that stays outside. An exposed steel flat top rusts quickly under rain and humidity, and the seasoning that protects it breaks down first. A good cover also blocks UV rays, dust, pollen and insect nesting, all of which shorten the life of the cooking surface. The exception is a griddle in a fully covered space that never sees weather.
Can you keep your Blackstone griddle outside?
Yes, you can keep a Blackstone griddle outside as long as it is covered when not in use and the seasoning is maintained. Outdoor owners with a good cover routinely report no rust after a full season. The cover matters most in freeze-thaw climates, where water trapped against the surface freezes and thaws repeatedly. Clean, dry and lightly oil the surface before any long storage period.
What can I put on my griddle to keep it from rusting?
Start by cleaning and drying the surface thoroughly, then apply a very light coat of cooking oil and let it sit before covering. Keep the griddle covered whenever it is not cooking, choose a cover with sealed seams and vents that let condensation escape, and never put a cover over a hot or warm surface. Store the griddle under a hard hood if you get heavy snow, since fabric covers alone will not handle snow load.
Should I cover my griddle in winter?
Yes, cover the griddle through winter if it stays outside. Snow and ice hold moisture against the steel, and repeated freeze-thaw cycles are the fastest route to surface rust. Before the first freeze, scrape and clean the surface, dry it completely, apply a light coat of oil, then fit the cover and cinch every strap. Inspect it once a month to check the fit and look for fabric cracking.
What is the difference between 420D and 600D covers?
Denier measures thread density, so 600D fabric is heavier and roughly more tear-resistant than 420D. In practice 420D is the entry-level standard that handles light rain and occasional use, while 600D resists tearing at corners and straps, lasts longer in full sun, and handles snow load better. Neither denier rating is waterproof on its own, so check for a coating and sealed seams separately.
How do I know what size griddle cover to buy?
Measure length, width and height of the griddle including side shelves in their deployed position, then compare those numbers against the cover dimensions rather than the griddle size in the product name. Most 36 inch covers measure 66 to 67 inch long by 22 to 28 inch wide. Check the excluded model list too, since many 36 inch covers will not fit the ProSeries, Culinary or cabinet-equipped models.
The Verdict
After putting twelve covers through the same criteria, the Blackstone 36 inch cover still wins on evidence rather than specification. A 4.8 average across more than 29000 reviews, buckle hardware that survives wind, and 600D double-layered polyester is a combination that very few aftermarket covers match, and if your griddle is that exact model the fit question disappears.
Buy the NettyPro if your griddle is fully exposed and you want sealed seams and hardware. Buy the Unicook if you have a 22 inch or 28 inch single-shelf griddle, because it is the only genuinely sealed design sized for a small station. The ULTCOVER is the answer in snow country, and the KINGLY 1000D is the one for full-sun decks.
Whichever you choose, check the excluded model list before you order, clean and lightly oil the surface before every long storage stretch, and give every strap a tug. That last thirty seconds is what keeps the best griddle covers for outdoor griddles doing their job for four or five seasons instead of one.
