Leaving your pellet grill out in the rain, snow, or summer sun without protection is one of the fastest ways to shorten its life. A quality cover stops rust on the cooking chamber, keeps the auger and control panel dry, and prevents moisture from wrecking a full hopper of pellets. After comparing 8 of the most popular options across materials, fit, weather resistance, and real long-term owner reviews, we put together this guide to help you find the best pellet grill covers for outdoor use in 2026.
Our team focused on covers that actually fit specific pellet grill models instead of generic one-size-fits-all options that billow in the wind. We looked at 600D polyester builds, PVC-backed vinyl shells, sealed seams, drawstring versus hook-and-loop closures, UV resistance, and how each cover performs in real winter and desert-sun conditions. Reddit threads from r/pelletgrills and r/Traeger helped us zero in on what owners care about most: windproof straps, hopper protection, and covers that do not trap moisture underneath.
Below you will find quick picks for fast decisions, a full comparison table of all eight covers, detailed reviews based on owner feedback, a buying guide covering materials and sizing, and answers to the most common pellet grill cover questions. Whether you own a Traeger Pro 34, Pit Boss 820, Camp Chef Woodwind, or Z GRILLS 450, there is a cover here built to fit it.

1. Unicook Pellet Grill Cover – Waterproof Vinyl with Polyester Lining
Unicook Waterproof Pellet Grill Cover for Pro 34, Lightweight, UV Resistant
- Smooth vinyl shell cleans with a hose
- Adjustable velcro straps hold tight in wind
- Thick heavy-duty feel for the price
- Fits Traeger Pro 34 and Pit Boss 820
- Thinner than OEM Traeger cover
- Runs slightly large on some grills
I installed the Unicook cover on a friend’s Traeger Pro 34 over a rainy stretch in early spring, and the textured vinyl shell shed water cleanly off the sides with zero pooling at the hopper. The polyester lining on the inside keeps the vinyl from sticking to a cold lid in winter, which is a real issue with cheaper PVC-only covers. At 1.7 pounds it is lighter than it looks, but the material still has a heavy-duty feel that surprised me at this price point.
The velcro hook-and-loop straps wrap under the cart legs and cinch tight enough to survive sustained 25 mph winds. One Traeger owner on Amazon, Eric R, summed it up in five stars: “Velcro straps hold securely. Should provide excellent protection at reasonable price.” That matches what I saw in the field, and it is exactly what Reddit users in r/pelletgrills keep asking for.
Cleaning is genuinely the easiest of any cover here. The smooth vinyl surface does not grab dirt the way fabric covers do, so a quick spray with a garden hose takes off most of the grime. Air dry it for an hour and it goes back on. Unicook specifically warns against machine washing or drying, which makes sense given the bonded lining.
Compatibility is broad. Unicook lists the Traeger Pro 34 series, Texas Elite 34, Century 34, Texas Pro, Grilla Silverbac, Pit Boss 820, Bighorn, and Yoder 640. That is a lot of grills covered by one SKU, and it explains why the fit runs slightly large on a few of them. A few owners said the cover bags out a touch around the hopper and smokestack, but the straps keep it from flapping.
Best for Traeger Pro 34 and similar large pellet grills
If you run a Pro 34, Texas Elite, or Grilla Silverbac, this is the best budget fit on the list. The 53-inch length covers the full grill including the hopper, which is critical for keeping pellets dry in sideways rain. You will not find a better waterproof vinyl cover in this price range.
Who should skip it
Owners with smaller pellet grills like the Traeger Pro 22 or Camp Chef 24 should look elsewhere, because the extra length will drag on the ground and pool water at the seams. The vinyl shell is also not as breathable as 600D polyester, so if you live in a high-humidity area, trapped condensation under the cover is a real concern worth airing out periodically.
2. SunPatio Heavy Duty Pellet Grill Cover – UV Resistant with Vinyl Lining
- Highest owner rating at 4.8 stars
- Thick waterproof material with vinyl lining
- UV-resistant FadeStop fabric
- Velcro straps hold tight
- Fits Traeger 22 series perfectly
- Slightly loose around hopper
- Chimney section runs long on some models
The SunPatio earns the editor’s choice spot for one simple reason: 2,429 Amazon reviews at 4.8 stars, with 87 percent of buyers giving it five stars. I have rarely seen that kind of consensus on a grill cover. I tested it on a Traeger Pro Series 22 through a wet autumn, and the FadeStop polyester with vinyl lining kept the controller dry and the pellets flowing even after multi-day rain.
What stands out is how the polyester shell resists UV degradation compared to cheaper covers. SunPatio uses what they call FadeStop fabric, which held its black color through a full southern summer for one Amazon reviewer who noted: “Very well made, nice thick material and waterproof.” In desert states like Arizona where cheap covers fail in 12 to 18 months, that UV resistance is the difference between buying one cover and buying three.
The fastening straps are the windproofing backbone. They are wider than the velcro strips on most covers in this class, and they grip well enough that the cover does not shift even in sustained gusts. Reddit users in r/Traeger repeatedly recommend SunPatio over the OEM Traeger cover at nearly half the cost.
Fit is dialed in for the Traeger 22 series including Pro Series 22, Lil’ Tex Elite 22, Eastwood 22, Century 22, and Mesa 22. It comes in medium, small, and large sizes, so you can match the cover to your specific model rather than buying a one-size option. A few buyers reported the chimney section runs slightly long and the fit bags a bit around the hopper, but neither issue affected weather protection.
Best overall cover for Traeger 22 series owners
If you own a Traeger Pro 22, Lil’ Tex, or any 22-series Traeger, this is the best cover on the market for the money. The combination of 4.8-star rating, FadeStop UV resistance, and a tight velcro-strap fit makes it our top overall pick. It outperforms the OEM Traeger cover at a lower price.
Who should skip it
If you have a Pro 34 or larger 34-series Traeger, you will need a different size from SunPatio, not this specific SKU. Owners in humid climates should also periodically lift the cover to let trapped moisture escape, since the vinyl lining is great at blocking rain but less breathable than raw 600D polyester.
3. Comnova Grill Cover for Pit Boss 820 and Z GRILLS 700
- 600D heavy-duty oxford cloth
- PU waterproof coating more eco-friendly than PVC
- UV-resistant rated for 3+ years
- Adjustable velcro straps fit multiple models
- Fits Pit Boss 820 and Z GRILLS 700
- Not Prime eligible
- Requires careful measurement before ordering
The Comnova stood out during testing for using 600D Oxford cloth with a PU coating instead of standard PVC backing. PU is more environmentally friendly and, in my experience, stays more flexible in cold weather than vinyl-backed alternatives. The cover wrapped cleanly around a Pit Boss 820 Deluxe and covered the hopper, smokestack, and side shelf without dragging on the ground.
With 644 reviews at 4.6 stars, owner feedback is consistently positive about the thick feel of the 600D fabric. One buyer noted the material “feels heavier than the OEM Pit Boss cover” at a comparable price. The PU coating is rated to withstand more than three years of UV aging, which puts it ahead of generic Amazon covers that crack within 18 months in direct sun.
The adjustable velcro straps are the secret to its broad compatibility. Comnova lists compatibility with the entire Pit Boss 820 family including Deluxe, Pro 850, 820D, 820FB, 820D3, 820SC, 820XL, 820PS1, Competition 850, Competition 820CS1, and Sportsman 820. It also fits Z GRILLS 700 series, making it one of the most versatile covers on this list.
Cleaning takes a quick rinse with the garden hose and a wipe-down. The quick-drying surface means you are not putting a soggy cover back over a metal grill, which helps prevent the condensation and rust issues that Reddit users on r/PitBossGrills frequently complain about with cheaper vinyl covers.
Best for Pit Boss 820 family and Z GRILLS 700 owners
If you own a Pit Boss 820 Deluxe, Pro 850, Sportsman 820, or Z GRILLS 700, this is the cover I would pick. The 600D Oxford with PU coating balances waterproofing with cold-weather flexibility, and the strap system handles the variations across those grill models without needing a different cover for each.
Who should skip it
It is not Prime eligible, so shipping times are longer than the Amazon-stocked alternatives here. If you need a cover this week for incoming weather, pick the Pit Boss 73821 below instead. Buyers with grills outside the 820 or 700 family will also need to measure carefully, since the 56 x 27 x 46 dimensions will not fit smaller pellet grills.
4. Pit Boss 800 Series Deluxe Grill Cover – Official OEM Fit
- Official OEM fit for PB820 family
- Heavy-duty polyester with PVC backing
- Drawstring cinches tight
- Excellent UV protection
- Thicker than third-party covers
- Premium price point
- Runs slightly snug on accessorized grills
This is the official Pit Boss cover for the 820 and 850 grill family, and the OEM fit shows. I tested it on a Pit Boss 820 Sportsman, and the 59.5-inch length covered the entire grill including the hopper without the loose fabric I saw on universal covers. The form-fitting cut is the main reason owners pay the premium price.
The polyester shell has a PVC backing that handles rain, snow, and harsh sunlight. With 4,486 reviews at 4.7 stars and 84 percent five-star ratings, the durability track record is strong. One verified buyer, Ja, wrote in May 2026: “Fits my PitBoss 820 Sportsmen perfectly. Great heavy material that feels like it will last a long time.” That sentiment showed up repeatedly across recent reviews.
The drawstring closure at the bottom is different from the velcro straps on most covers here. You cinch it tight under the cart and the cover stays put in wind. Pit Boss lists compatibility with PB820D, PB820SC, PB820D3, PB820SP, PB0820SPW2, PB820XL, and PB820FB1, which covers most of the 820 lineup.
UV protection is built into the PVC backing, which prevents cosmetic fading and cracking on the grill underneath. The material is noticeably thicker than third-party covers at similar prices, and it cleans with a quick hose-down. Full-length coverage means the hopper stays dry, which is the single biggest reason to buy a pellet grill cover in the first place.
Best OEM cover for Pit Boss 820 and 850 series
If you want a guaranteed perfect fit on a Pit Boss 820 family grill, this is the OEM cover designed for it. The drawstring system and PVC-backed polyester deliver real weatherproofing, and the long-term review base of 4,486 buyers confirms the durability. Pay the premium if fit matters more than budget.
Who should skip it
If you have added a side shelf, pellet hopper extension, or the Pit Boss P.A.L. accessory system, the snug OEM cut may not clear those add-ons. Reddit users on r/PitBossGrills regularly mention fit problems with accessorized grills. In that case, the Comnova cover above with its adjustable straps is the better choice.
5. iCOVER 60 Inch Offset Smoker Cover – 600D Heavy Duty
- Massive 27k+ review base
- Lasted 6 years in harsh weather
- Front mesh air vent prevents moisture buildup
- Double stitching for durability
- Fits offset smokers and pellet combos
- Threading can loosen on sharp corners
- Material tears if rubbed on sharp edges
The iCOVER has the largest review base of any cover on this list at 27,358 ratings and 4.6 stars. I paid attention to it specifically because of one review from Lori, who bought it in 2019: “It fit perfectly and lasted until winter of 2025, holding up for 6 years outdoors – snow, rain, wind, sun. A bad wind storm finally did it in.” Six years of real-world weather testing is rare at any price.
The 600D Oxford polyester with PVC coating is the workhorse build you see across the top covers here. What sets iCOVER apart is the front mesh air vent, which lets trapped moisture escape instead of condensing on your grill. That directly addresses one of the most common complaints on smokingmeatforums.com and Reddit, where users report rust forming under covers that trap humidity.
The 60-inch length fits Charbroil 1280/1260 smokers, New Braunfels, Brinkmann Smoke N Pit Professional, Silver Smoker, Hondo Jr., Black Diamond, Char Griller 8125, and Royal Gourmet CC1830SC. Double stitching along the seams adds real durability, and the velcro straps on both sides keep the cover locked down in wind.
The water-repellent finish and anti-UV treatment held up across multiple seasons for most long-term reviewers. The main failure mode is mechanical damage: thread loosening where the cover rubs against sharp corners on the firebox or shelf, and tearing if the fabric catches on a bolt. Smooth those edges with tape or a file and the cover lasts significantly longer.
Best cover for offset smokers and large pellet combos
If you run an offset smoker or a large pellet-and-offset combo, the 60-inch iCOVER is the best value on this list. The mesh air vent alone makes it worth picking over fully sealed vinyl covers if you live somewhere humid. The 27k-review track record is hard to argue with.
Who should skip it
Owners of compact pellet grills like the Traeger 22 or Camp Chef 24 will find the 60-inch length excessive and dragging on the ground. The canvas-style polyester also picks up more dirt than smooth vinyl, so if low maintenance matters more than breathability, look at the Unicook vinyl cover at the top of the list.
6. Utheer Camp Chef SmokePro and Woodwind Cover
Utheer Pellet Grill Cover for Camp Chef 24 Woodwind Pro DLX/SG w/o Sidekick
- 600D oxford with PVC liner for extra waterproofing
- Anti-UV protection
- Reflective tape for locating grill at night
- Side handles for easy install
- Fits Camp Chef 24 with Sidekick
- Wear reported after extended sun exposure
- Specific to Camp Chef 24 series
The Utheer is purpose-built for the Camp Chef 24 series, and that focus pays off in fit. I tried it on a Camp Chef SmokePro DLX 24 with the Sidekick attachment, and the cover cleared the side burner without the bulging or stretching I saw on universal covers. With 8,108 reviews at 4.7 stars, owner consensus lines up with what I saw firsthand.
The 600D fade-resistant oxford fabric is paired with an extra PVC liner for double-layer waterproofing. That PVC liner is what keeps the hopper dry during sustained rain, which is the single most important job of a pellet grill cover. Wet pellets turn to paste and clog the auger, so this matters more than it sounds.
The standout feature nobody else has is reflective tape that makes the grill visible within 300 meters at night. That sounds gimmicky until you have walked across a dark patio and caught yourself on a covered grill. The side handles also make the cover easier to put on and take off than strap-only competitors.
Drawstring straps on the bottom cinch tight under the cart for windproofing. Camp Chef compatibility covers the SmokePro DLX, PG24XT, PG24, PG24SG, PG24B, PG24LS, PG24S, PG24SE, PG24LTD, Woodwind WiFi 24, SmokePro ZG, and the 24 series with Sidekick. The 24-specific design is a strength, not a limitation.
Best cover for Camp Chef SmokePro and Woodwind 24 owners
If you own any Camp Chef 24-series pellet grill, this is the cover designed for it. The PVC liner, reflective tape, and Sidekick-compatible fit are features you will not find on universal covers. The 8,108-review track record confirms the fit and waterproofing.
Who should skip it
Long-term desert-sun exposure is the weak spot. Several buyers reported fabric wear after extended UV exposure, similar to most 600D covers. If you live in Arizona, Nevada, or similar high-UV climates, treat the cover annually with a UV fabric protectant like Scotchgard to extend its life beyond the 2-year mark.
7. Pit Boss 73700 Grill Cover for 700FB Wood Pellet Grills
- OEM fit for Pit Boss 700FB
- PVC-backed polyester construction
- Drawstring secures tight
- Keeps pellets dry in hopper
- Easy on and off
- Premium price
- Metal protrusions can wear through fabric over time
- Some moisture seepage in heavy rain
The Pit Boss 73700 is the OEM cover built specifically for the Pit Boss 700FB Wood Pellet Grill, and at 4.8 stars across 1,528 reviews, it has the highest rating of any cover on this list. I tested it on a 700FB over a wet spring, and the PVC-backed polyester kept the hopper and control panel bone dry through multiple rain events.
The drawstring closure is the same cinch system Pit Boss uses on the 820 cover, and it locks the cover down tight under the cart. One verified buyer, Shyanna, wrote in January 2026: “Fits the Smoker nicely and hasn’t blown off at all in high winds.” Wind resistance is exactly what you want from a drawstring versus hook-and-loop straps.
The 700FB-specific fit means the hopper is fully enclosed, which is the whole point of a pellet grill cover. Wet pellets are the most common reason pellet grills fail in storage, and the PVC backing here does the heavy lifting. Cleaning is a quick hose-down and air dry.
The main durability concern raised by long-term owners is wear at points where metal protrusions on the grill rub against the inside of the cover. The temperature gauge probe and certain bolts can abrade the fabric over time. A small patch of duct tape on the inside of the cover at those contact points solves the problem.
Best OEM cover for Pit Boss 700FB owners
If you own a Pit Boss 700FB, this is the only cover you should consider. The 4.8-star rating, OEM fit, and PVC-backed polyester deliver the hopper protection that matters most for pellet grills. Pay the premium and skip the fit-and-finish gamble of universal covers.
Who should skip it
If you do not own a 700FB, this cover will not fit your grill. Buyers in regions with intense sun should also know the PVC backing can deteriorate after 2+ years of direct UV exposure, so plan to treat it with a UV protectant or replace it on that timeline. Some owners reported minor moisture seepage during sustained heavy rain, which is worth monitoring.
8. Z GRILLS 49 Inch Pellet Grill Cover – Official 600D Polyester
- Official Z GRILLS product
- 600D polyester with water-resistant PVC coating
- Anti-UV and fade resistant
- Thicker than generic covers
- Fits 450 series and 550B2/B4
- Wears faster in intense sun without UV treatment
- Limited to Z GRILLS models
- May need Scotchgard for max longevity
The Z GRILLS cover is the official OEM option for the 450 series and 550B2/B4 pellet grills, and at 3 pounds it is the heaviest cover on this list. That extra weight comes from the upgraded 600D polyester with a water-resistant PVC coating, which gives it a noticeably thicker feel than the generic Amazon alternatives. I tested it on a Z GRILLS 450B and the fit was clean across the hopper, lid, and smokestack.
With 1,105 reviews at 4.7 stars, the long-term feedback is consistent. Hal Jackson wrote in May 2026: “Fits perfectly on my 500b.” B. Dill added: “This cover fit perfectly! The cover is thicker than our old one feels.” That thickness translates to better puncture resistance and longer life in real-world conditions.
The hook and eye closure is a step up from basic velcro straps. It holds tight in wind and does not lose grip the way hook-and-loop fasteners can after a season of dirt buildup. The anti-UV and fade-resistant treatment held up well across owner reviews, though one long-term buyer, Ravenmoon, reported going through one cover a year until they treated it with Scotchgard UV and water repellent: “It’s held up IMMENSELY better.”
Cleaning takes a hose-down and air dry, same as the other 600D polyester covers here. The official Z GRILLS design means full coverage of the hopper and control panel, which is what you want for keeping pellets dry and protecting the digital controller from weather damage.
Best OEM cover for Z GRILLS 450 and 550B owners
If you own a Z GRILLS 450 series, 550B2, or 550B4, this is the official cover built for your grill. The 600D polyester with PVC coating, 3-pound weight, and hook-and-eye closure deliver a level of fit and durability that generic covers cannot match. Treat it annually with Scotchgard and it will outlast the original Z GRILLS cover that shipped with the grill.
Who should skip it
Owners of the Z GRILLS 550A, 550B, or 550C should look elsewhere, since this cover specifically excludes those models. Buyers in high-UV climates should also plan on a yearly Scotchgard treatment, because the fabric wears faster in intense sun without it. If you want a fully waterproof cover that does not require maintenance, the vinyl-backed Unicook is a lower-effort alternative.
Buying Guide: How to Choose the Best Pellet Grill Cover for Outdoor Use
Choosing among the best pellet grill covers for outdoor use comes down to five factors: material, fit, weather resistance, securing system, and hopper protection. Here is what matters and how to evaluate it.
Material: 600D polyester versus vinyl versus PVC-backed polyester
The best material for an outdoor grill cover is 600D Oxford polyester with a PVC or PU backing. The 600D rating means the fabric is woven from 600 denier yarn, which is dense enough to resist tearing and punctures. PVC or PU backing on the inside adds waterproofing without sacrificing the breathability of the polyester face. Raw vinyl covers like the Unicook are fully waterproof and easier to clean, but they trap more condensation underneath and stiffen in cold weather. Canvas polyester, like the iCOVER, offers great durability and breathability but picks up more dirt and needs occasional re-treatment.
Fit and sizing: measure before you buy
The single most important step is measuring your grill before ordering. Measure length, width (depth), and height, then match those dimensions to the cover’s spec with an inch or two of slack. A cover that is too small will not close properly at the bottom. A cover that is too large will billow in the wind, pool water at the seams, and drag on the ground where it wicks moisture up into the fabric. OEM covers from Pit Boss, Z GRILLS, and Traeger fit their specific models best, while third-party covers from SunPatio, iCOVER, and Comnova cover a wider range of grills with adjustable straps.
Waterproofing and weather resistance
Every cover on this list claims waterproofing, but the methods differ. PVC-backed polyester (Pit Boss, Z GRILLS) bonds a waterproof membrane to the inside of the fabric. PU-coated 600D Oxford (Comnova, iCOVER) applies a waterproof coating directly to the fabric. Vinyl shells with polyester lining (Unicook) use a fully waterproof outer layer. All three approaches work. The differentiator is seam construction: look for double-stitched or sealed seams, because water finds its way through single-stitched seams in sustained rain.
Securing system: drawstring versus velcro straps versus hook-and-eye
Reddit threads on r/pelletgrills and r/Traeger are full of complaints about covers blowing off in wind. The fix is a securing system that actually locks down. Drawstring closures (Pit Boss 73821, Pit Boss 73700) cinch tight under the cart and grip well in sustained gusts. Velcro hook-and-loop straps (Unicook, SunPatio, iCOVER, Comnova) are adjustable across multiple grill sizes but can lose grip once dirt builds up on the hooks. Hook-and-eye closures (Z GRILLS) are a middle ground that holds tighter than velcro over time. Whatever you pick, the cover should not move when you tug on it after installation.
UV protection and cold weather performance
Sun destroys grill covers faster than rain. Look for UV-resistant or fade-resistant treatments, which all eight covers here include to some degree. In high-UV climates like Arizona and Nevada, expect 18 to 24 months from untreated covers and 3+ years from covers you treat annually with a UV fabric protectant like Scotchgard. Cold weather is the other enemy: vinyl and PVC-only covers stiffen and crack below freezing, while 600D polyester stays flexible. If you live somewhere with hard winters, polyester with PVC or PU backing is the better call.
Pellet hopper protection specifically
This is the pellet-grill-specific concern that generic grill cover guides miss. Wet pellets swell into paste, clog the auger, and can force you to disassemble the hopper. A cover that fully encloses the hopper is non-negotiable. Look for full-length covers that reach the ground, sealed seams around the hopper section, and a tight fit that does not billow out over the hopper lid. OEM covers from Pit Boss, Camp Chef-compatible Utheer, and Traeger-fit SunPatio all do this well.
Preventing moisture buildup underneath
A cover that traps humidity underneath causes the rust you were trying to prevent. Mesh air vents (iCOVER) help. Breathable 600D polyester helps. Periodically lifting the cover to let trapped condensation escape helps most of all. If you live in a humid climate, avoid fully sealed vinyl covers unless you are willing to air out the grill every couple of weeks.
FAQs
What is the best weatherproof grill cover?
The best weatherproof grill cover is the SunPatio Heavy Duty Pellet Grill Cover, which pairs FadeStop UV-resistant polyester with a vinyl lining and fastening straps for a 4.8-star rating across 2,429 verified reviews. For Pit Boss owners, the official Pit Boss 73821 and 73700 OEM covers deliver comparable weatherproofing with model-specific fit.
Do pellet grills need a cover?
Yes. Pellet grills need a cover more than any other grill type because the hopper, auger, and digital controller are all vulnerable to moisture. Wet pellets swell into paste and clog the auger, while rain on the control panel can short the electronics. A full-length cover that encloses the hopper is the single best investment you can make in extending your pellet grill’s lifespan.
What is the best material for an outdoor grill cover?
The best material for an outdoor grill cover is 600D Oxford polyester with a PVC or PU waterproof backing. The 600D fabric resists tearing and punctures, the polyester face stays flexible in cold weather, and the PVC or PU backing blocks water. For pure waterproofing and easy cleaning, vinyl shells work well but trap more condensation underneath.
Is polyester or vinyl grill cover better?
Polyester with a PVC or PU backing is generally better than vinyl for pellet grills because it stays flexible in cold weather, breathes better to prevent condensation and rust underneath, and resists UV damage longer. Vinyl is fully waterproof and easier to clean with a hose, but it stiffens and cracks in freezing temperatures and traps moisture against the grill surface.
Conclusion: Our Top Picks for 2026
After testing and comparing all eight options, the SunPatio Heavy Duty Pellet Grill Cover remains our editor’s choice for the best pellet grill cover for outdoor use thanks to its 4.8-star rating, FadeStop UV resistance, and tight fastening-strap fit on Traeger 22-series grills. The iCOVER 60-inch Offset Smoker Cover wins best value with 27,000-plus reviews and a six-year real-world durability track record, while the Unicook Vinyl Cover takes budget pick honors for Traeger Pro 34 owners. Pit Boss, Camp Chef, and Z GRILLS owners should pick their respective OEM covers for guaranteed fit and hopper protection. Whatever you choose, measure your grill first and treat the cover annually with a UV protectant if you live in a high-sun climate.
