- Excellent secure fit for Traeger Pro 34/780 and many similar grills with adjustable windproof straps

Cons
- Sizing is specific at 53x22x40 inches, not compatible with some models like Z Grills 550A/450 and Yoder YS640s so measuring is required
- Heavier and bulkier than lightweight vinyl covers, needs more storage space when folded
- Only available in one color and size, limiting options for other grill types
The GuardKove 1000D Heavy Duty Grill Cover is a 53x22x40 inch cover engineered specifically for the Traeger Pro 34, Pro 780 and other similarly sized barrel-style pellet grills. It is ideal for owners who keep their grill outdoors year round and want premium protection without the cost of a branded OEM cover.
In real world use, its standout feature is the upgraded 1000D Oxford fabric that offers twice the tear resistance of standard 420D to 900D covers. Combined with a triple waterproof system featuring a dense outer layer, PVC lining and heat-sealed tape, it reliably blocks rain and snow to prevent rust and pooling.
Build quality is a clear step up, with UPF 50+ UV resistance that blocks nearly all harmful rays to prevent fading and cracking for years. The thoughtful design includes adjustable buckle straps on both sides to lock the cover against wind and a side zipper that lets one person install or remove it easily.
The main limitation is fit specificity, as the cover is not universal and will not fit certain models like the Z Grills 550A or Yoder YS640s. Buyers must measure carefully before ordering, and the heavier 1000D material is bulkier to fold and store than thin vinyl alternatives.
Overall, the GuardKove delivers outstanding durability, weatherproofing and ease of use for its class. For Traeger Pro 34/780 owners and those with compatible pellet grills, it is a highly recommended upgrade that protects your investment through all seasons.

The Comnova Grill Cover is a 56-inch heavy-duty cover built specifically for Pit Boss 820 and 850 series pellet grills and Z Grill 700 series smokers. It is designed for owners who need reliable outdoor protection without paying for the branded OEM cover, offering a precise fit for popular models like the 820 Deluxe, Pro 850, Competition and Sportsman series.
In real world use, it excels at all-weather defense. The waterproof PU coating keeps heavy rain and snow out, while the UV-resistant layer prevents fading and cracking from prolonged sun exposure. Owners report it stays secure through strong winds thanks to the side velcro straps, and it holds up well through year-round outdoor storage with frequent on and off use.
Build quality centers on 600D Oxford cloth, which feels softer and more breathable than stiff PVC alternatives yet remains tough against tears. The seams are sturdy, the fabric dries quickly after rain, and the PU coating adds eco-friendly water resistance. The black finish looks clean and the material is easy to handle when covering or removing the grill.
There are a few tradeoffs to consider. The cover is slightly thinner than the factory original, and the design may leave the very bottom of the legs and casters exposed on some models. You also need to let the grill cool for 10 to 15 minutes before covering, which is standard for this type of fabric.
Overall, the Comnova 600D Pellet Grill Cover delivers outstanding value, fit and weather protection for Pit Boss and Z Grill owners. If you want a durable, waterproof and wind-resistant cover that fits correctly and is easy to maintain, this is a smart and proven choice.

For the best fit, measure your grill carefully before ordering and compare to the 56 x 27 x 46 inch dimensions. The adjustable velcro straps allow you to cinch the cover for a snug fit on slightly smaller frames.
Always allow your pellet smoker to cool for 10 to 15 minutes before covering to protect the fabric. To clean, simply rinse with water, wipe with a soft cloth and let it air dry in the sun before next use.

The Unicook Pellet Grill Cover is a full length 53 inch cover built specifically for Traeger Pro 34 series and compatible pellet grills. It is ideal for owners of Traeger Texas Elite, Pit Boss 820, Grilla Silverbac and similar 34 series models who want reliable year round outdoor protection.
Its standout feature is the upgraded 2024 waterproof textured vinyl shell paired with a heavy duty polyester lining. This combination blocks rain, snow, sun and dirt while the soft inner liner prevents the cover from sticking to the grill surface.
Build quality reflects Unicook's 20 years of experience, with a durable black vinyl exterior that resists tearing and wipes clean easily. Adjustable hook and loop fastening straps create a snug, windproof fit that stays secure even in gusty conditions.
There are a few limitations to consider. The cover is not machine washable and must be hosed off and air dried, and you must let the grill cool completely before covering. The sizing is also specific to 34 series grills, so it will not fit compact or extra large models.
Overall, this cover delivers premium all weather protection at a much lower cost than OEM options. For pellet grill owners seeking a durable, waterproof and easy care cover with a precise fit, it is an excellent value choice.

Buying Guide: How to Choose a Pellet Grill Cover That Actually Protects
Fabric Density and Waterproof Construction
Fabric weight tells you a lot about durability. The 1000D Heavy Duty Grill Cover for Traeger Pro from GuardKove uses upgraded 1000D high density Oxford cloth with a PVC waterproof lining and heat sealed tape, which offers far greater tear resistance than standard 420D or 600D options.
If you prefer a softer, more breathable feel, the Comnova Grill Cover for Pit Boss 820-850 uses 600D Oxford cloth with a PU coating and UV resistant coating. It blocks rain and snow while remaining flexible and environmentally friendlier than vinyl. For a vinyl approach, the Unicook Pellet Grill Cover Compatible for Traeger pairs a textured waterproof vinyl shell with a soft polyester lining to prevent sticking and keep moisture out.
Look for triple layer protection when you store your grill uncovered for months. High density outer fabric, an inner waterproof membrane and sealed seams prevent the slow seepage that causes rust inside pellet hoppers and augers. If you are building out a full backyard kitchen, pair your cover choice with inspiration from the best pizza oven outdoor for backyard setups for complementary weatherproofing ideas.
Fit Accuracy and Compatibility
Pellet grills vary widely by width, depth and height, so measure before you order. The GuardKove and Unicook models both measure 53″W x 22″D x 40″H and are designed for Traeger Pro 34 and Pro 780, Texas Elite 34, Century 34, Grilla Silverbac and similar barrel style smokers. The Comnova model is larger at 56″W x 27″D x 46″H and is tailored for Pit Boss 820 Deluxe, Pro 850 series and Z Grill 700 series.
A cover that is too tight will stress seams and zippers, while one that is too loose will pool water and catch wind. We recommend measuring from the widest point of the side shelf to the opposite end, including handles and chimneys. Check your grill manual for overall dimensions and compare directly to the cover specs rather than relying on model name alone.
Compatibility notes matter. GuardKove explicitly notes it is not for Z Grills 550A or 450 and certain extra large frames, while Comnova lists specific Pit Boss 820 variants like 820D, 820FB and Competition 850. Choosing a cover mapped to your exact grill prevents returns and ensures a clean drape. You can find more sizing and accessory tips alongside our best BBQ tools set recommendations.
Wind Security and Stay-Put Design
Wind is the most common reason covers fail. All three options here address it, but in different ways. GuardKove adds adjustable wind resistant buckle straps on both sides to lock the cover snugly around the barrel, while Unicook uses adjustable sturdy fastening straps for a similar secure fit.
Comnova takes a slightly different approach with adjustable Velcro style magic bands on each side that let you cinch the cover for different pellet smoker widths. This flexibility is helpful if you share a cover between two similar sized grills or if your grill has an extended side table. In gusty locations, buckles tend to hold firmer over time than Velcro, which can collect lint.
Consider your storage location. On an open deck or near a fence line where wind tunnels form, prioritize buckle straps and a weighted hem. If your grill sits in a sheltered patio, Velcro adjustments may be enough. For troubleshooting wind related grill issues, our gas grill 4 burner won’t light troubleshooting guide also covers how exposure affects ignition and airflow.
Ease of Use, Cleaning and Long Term Durability
Serious grillers use their grill often, so the cover must be easy to remove and replace solo. GuardKove includes a convenient side zipper opening so you can drape and remove the cover without wrestling the entire grill. That detail is especially useful in cold weather or when the grill is still warm.
Cleaning should be simple. Comnova uses a quick drying cloth surface that rinses clean with water and wipes dry, while Unicook features a smooth vinyl shell you can hose off and air dry in the sun. Both brands advise letting the grill cool for 10 to 15 minutes before covering and avoiding machine washing, which preserves waterproof coatings.
Long term durability comes from UV resistance as much as waterproofing. GuardKove advertises UPF 50+ fabric that blocks nearly all UV rays and resists fading and cracking for years, and Comnova has been assessed for extended UV aging performance. If you maintain other outdoor equipment, you will appreciate similar low maintenance care routines highlighted in our Composting & Soil Health and Garden & Greenhouse resources for seasonal gear upkeep.
Final Thoughts
For maximum tear resistance and a secure, zippered fit on Traeger Pro 34 and similar mid size barrel grills, the 1000D Heavy Duty Grill Cover for Traeger Pro stands out, while those with larger Pit Boss 820 or 850 series grills will appreciate the roomier, breathable protection of the Comnova Grill Cover for Pit Boss 820-850 for year round coverage.
Frequently Asked Questions
What size pellet grill cover do I need for a Traeger Pro 34 or Pit Boss 820?
Measure your grill at its widest, deepest and tallest points including shelves and handles. Covers sized at 53″W x 22″D x 40″H typically fit Traeger Pro 34, Texas Elite 34 and similar 34 series models, while 56″W x 27″D x 46″H is the safer match for Pit Boss 820 Deluxe and Pro 850 units. Always compare your actual measurements to the listed dimensions before ordering.
Are vinyl or Oxford cloth pellet grill covers better for waterproof protection?
Both can be fully waterproof when constructed correctly. Vinyl shells like the Unicook option excel at shedding rain and wiping clean, while Oxford cloth with PU or PVC coatings like Comnova and GuardKove offers more breathability and tear resistance. For serious grillers storing grills outdoors in all seasons, sealed seams and a waterproof lining matter more than the outer fabric alone.
How do I keep my pellet grill cover from blowing off in strong wind?
Choose a cover with adjustable straps and use them every time you cover the grill. Buckle straps provide the most secure hold, while Velcro bands let you fine tune tension for a snug fit. Position your grill near a windbreak when possible and ensure the cover hem sits evenly around the base to reduce lift.
How should I clean and care for my pellet grill cover in 2026?
Rinse the cover with water to remove dust and debris, wipe with a soft cloth and air dry in the sun before reuse. Avoid machine washing or high heat drying, which can damage waterproof coatings. Allow your grill to cool completely before covering and periodically check straps and seams, a habit similar to the maintenance steps in our how to use compost tumbler dual chamber guide for outdoor gear longevity.
