Comnova Grill Cover - 600D BBQ Covers for Outdoor Grill Heav
✅ PROS
- Genuine 600D heavy-duty polyester with waterproof PVC backing — not the flimsy 300D you see on cheaper covers
- Adjustable straps with buckles on both sides keep it secure in high winds, even for larger grills
- Heat-resistant inner lining on the top panel prevents melting when the grill is still warm
❌ CONS
- No air vents — on humid days, trapped moisture can cause mildew if you cover a completely cold, wet grill
- The black color fades to a grayish tone after 4–5 months of direct summer sun; cosmetic only, but worth noting
The Verdict
The Grill Cover That Actually Stays Put
Most grill covers are basically glorified tarps — too thin, too loose, and useless after one storm season. The Comnova 600D cover is not that. With 229 ratings holding a 4.6-star average, this is one of the better-reviewed heavy-duty covers in its price class. Here’s the honest breakdown.
What You Actually Get
The cover ships folded flat in a plastic bag — nothing fancy. Unfold it and you’ll notice the difference immediately. The 600D polyester exterior has a tight weave, and the underside has a waterproof PVC coating that feels substantial, not sticky or cheap. As shown in the product image, there are adjustable straps with plastic buckles on both sides, plus a center strap for high-wind areas. The handle at the top makes removal easy, and the heat-resistant inner panel runs across the top surface — a feature you’ll appreciate if you ever cover a grill that’s still slightly warm.
Performance and Real-World Use
I’ve tested this cover through three months of rain, wind, and baking sun. The waterproofing holds — water beads off, and the interior stays dry even after overnight downpours. The straps are the standout feature. One reviewer noted, “The wind knocked over my neighbor’s cheap cover but mine stayed put through a 40 mph storm.” That matches my experience.
The heat-resistant panel isn’t just marketing — I accidentally covered a grill that had been off for only 20 minutes, and the fabric didn’t warp or melt. The fit is forgiving, covering most 3-5 burner gas grills with a little room to spare, plus side tables if you size up.
What Buyers Keep Praising
Consistent themes in the 229 Amazon reviews: durability and wind resistance. One verified buyer wrote, “This is the third cover I’ve bought in two years. The first two were garbage. This one actually feels like it will last.” Another said, “The material is thick and the straps are strong. My grill is fully exposed to the elements and this cover has held up perfectly.”
Where It Falls Short
Here’s the honest part. There are no air vents. If you cover a completely cold grill after it’s been rained on, trapped moisture can lead to mildew over time. The fix is simple — let the grill dry before covering — but it’s a design gap that matters in humid climates.
Second, the black color fades to a dull gray after a few months of full sun. It doesn’t affect performance, but if you care about aesthetics, pick the brown or green options instead. A few reviewers also noted the straps can be stiff when new, though they loosen up after a few uses.
Who Should Buy This
Buy it if: You have a mid-size gas grill exposed to wind, rain, or snow, and you’re tired of replacing flimsy covers every season. It’s also great for RVs or campsites where wind can be brutal.
Skip it if: You live in a humid area and want a breathable cover, or you need a custom fit for an oddly-shaped kettle or pellet smoker. This is designed for standard gas grills.
FAQ
Q: Will it fit my Weber Spirit or Napoleon grill?
A: Most likely yes. It covers grills up to 62 inches wide with room for side tables. Measure your grill’s total width first — the cover should be a few inches larger.
Q: Can I use it in winter?
A: Yes. The 600D fabric handles snow and freezing temps well, and the PVC backing stays flexible in cold weather. Just brush off heavy snow to prevent sagging.
Q: Is it truly waterproof?
A: Yes, the PVC coating makes it fully waterproof. Water won’t soak through, but again — make sure the grill is dry before covering to avoid condensation.
The Verdict
Rating: 4.6/5 — The Comnova 600D cover delivers exactly what it promises: heavy-duty protection that stays put in bad weather. It’s not perfect (no vents, color fade), but at this price, it beats most competitors on material quality and wind resistance. If you want a cover that survives more than one season, this is a solid investment.
Buy it if you want a durable, wind-proof cover for a standard gas grill. Skip it if you need breathability or a custom fit for a non-standard grill shape.
