Comnova 600D Wood Pellet Grill Cover for Traeger - Waterproo
✅ PROS
- True 600D polyester with a waterproof coating that holds up through heavy rain without soaking through
- Adjustable hem cords on both sides let you cinch it tight, so it won't blow off in gusty conditions
- Fits Traeger Ironwood, Pro Series, and Pit Boss units up to roughly 50 inches wide without being baggy
❌ CONS
- No built-in venting — in humid climates, trapped moisture can cause mildew if the grill is stored hot
- The buckle straps are functional but feel a bit flimsy compared to the cover's overall build quality
The Verdict
If you’ve dropped $800–$1,500 on a pellet grill, the last thing you want is to watch the hopper lid rust or the paint bubble after one wet season. The Comnova 600D Wood Pellet Grill Cover is aimed squarely at that problem. At 4.2 stars from 210 Amazon ratings, it’s not the flashiest cover on the market — but it’s a solid, no-nonsense option that does the job without costing Pit Boss money.
What You Actually Get
The cover ships folded into a compact package with no carrying bag — just the cover itself. It’s made from 600D polyester with a waterproof coating on the interior. For context, that’s the same material class used in mid-range truck tonneau covers and heavy-duty patio furniture covers. As shown in the product image, it has an adjustable hem with drawstrings on both sides plus two buckle straps near the bottom.
The dimensions are generous. It’s designed to fit grills up to about 50 inches wide and 42 inches tall, which covers most Traeger Pro Series, Ironwood, and Pit Boss vertical pellet smokers. If you have a larger model like the Traeger Timberline XL, measure your grill first — this will likely come up short.
Real-World Performance
The waterproofing is the headline feature, and it delivers. Multiple reviewers note that after heavy rainstorms, the cover stayed dry on the inside. One buyer wrote: “Left it out through three straight days of rain in the Pacific Northwest. Opened the cover and the grill was bone dry. No pooling on top either — the slight dome shape sheds water well.”
The fit is where this cover earns its keep. The adjustable hem cords on both sides let you tighten it around the base of the grill, which prevents the “parachute effect” when wind gets underneath. A reviewer with a Pit Boss 820 confirmed: “Fit my Pit Boss 820 perfect. The drawstrings pulled it tight around the legs so it didn’t blow off during a windstorm.”
I’d caution against storing the grill immediately after use. The cover lacks venting, so if you close it over a still-warm grill, condensation forms and can lead to mildew inside. Let the grill cool completely before covering.
Where It Falls Short
The most common complaint in the ratings is the strap hardware. The buckles feel lighter than the fabric — one reviewer noted theirs snapped after about four months of regular use in a windy area. It’s not a dealbreaker, but if you live somewhere with persistent wind, plan to add a bungee cord or two for extra security.
The lack of venting is the bigger functional issue. In humid climates like Florida or the Gulf Coast, moisture can get trapped between the cover and the grill, especially if you cover it while slightly warm. If you live in a high-humidity area, this is worth factoring in — some users solve it by propping the cover slightly open at the bottom.
Who Should Buy This
Buy it if: You have a Traeger Pro Series, Ironwood, Pit Boss, or similar mid-size pellet grill and want reliable rain protection at a reasonable price. It’s also a solid choice if you’ve had cheap covers blow off or tear after one season.
Skip it if: You have an oversized grill (over 50 inches wide), store your grill in a garage or covered patio (you don’t need the waterproofing), or you’re in a high-humidity climate and want a cover with built-in vents.
FAQ
Will this fit my Traeger Pro 575? Yes. The Pro 575 is roughly 47 inches wide, well within the 50-inch limit. The adjustable hem lets you cinch it tight around the base.
Is it truly waterproof or just water-resistant? It’s coated with a waterproof layer, not just a water-repellent spray. Reviews confirm it handles heavy rain without soaking through. That said, no cover is 100% waterproof forever — expect the coating to degrade after 2–3 seasons of direct sun exposure.
Can I leave it on during winter? Yes, the 600D fabric handles freezing temps without cracking. Just brush off heavy snow accumulation to prevent the fabric from stretching under the weight.
The Verdict
Rating: 4.2/5
The Comnova 600D cover hits the essentials: it’s waterproof, fits mid-size pellet grills well, and stays put in wind thanks to the adjustable hem. The flimsy buckles and lack of venting keep it from being a five-star product, but for the price, it’s a genuinely good value. If you’ve been through a cheap cover that disintegrated after one season, this is a worthwhile upgrade that should last you a few years.
