Best Grill Covers of 2026What 61 reviewers actually think, trust-weighted

Grill covers are a low-cost insurance policy for an expensive grill, but the marketing claims ('heavy-duty,' 'waterproof,' '600D') vary wildly in how well they hold up. This roundup is a trust-weighted synthesis of what verified-purchase reviewers, mainstream outlets, and specialist grilling communities have already written, with the most weight given to long-running subreddit consensus and high-volume retailer reviews. We did not test these covers ourselves; we read across the reviewers and surfaced where they agree and where they conflict.

Frequently asked

5 questions
Are off-brand grill covers better than the manufacturer's own?
Across specialist communities like r/grilling and r/webergrills, the recurring consensus is that third-party covers from brands like Unicook, Classic Accessories (Ravenna), and KingKong often outlast and outperform the official Weber cover at a fraction of the price. Multiple high-trust threads describe Weber-branded covers cracking or fading within a couple of seasons, while several owners report 3-7 years from cheaper alternatives. That said, fit matters: a model-specific cover seals better against wind than a generic one.
What does '600D' mean and does it matter?
600D refers to the denier (thread density) of the polyester fabric; higher numbers generally mean thicker, more tear-resistant material. Specialist-subreddit reviewers note that some Amazon listings overstate their denier, so brands like DEK and Unicook get praised specifically for using the polyester weight they advertise. For most climates a genuine 600D cover with a waterproof coating is plenty; very wet or sun-baked regions benefit from heavier fabric plus UV inhibitors.
Do grill covers cause rust or mold?
This is a real, repeatedly cited downside. High-trust community threads warn that fully waterproof covers can trap condensation, leading to mold or rust if a grill is put away warm or stored without ventilation. Covers with mesh air vents and a snug-but-breathable fit are widely recommended to let moisture escape, and several reviewers suggest letting the grill fully cool and dry before covering.
How do I keep a grill cover from blowing off in the wind?
Reviewers consistently flag wind as the biggest failure point — one r/grilling poster described a covered grill tumbling 15 feet in a storm. Covers with adjustable straps, drawstring hems, and windproof buckles or clips fare best. Snug fit and side-tie-downs come up far more often than fabric thickness when owners describe what actually keeps a cover in place.
How long should a grill cover realistically last?
Across the reviewers we read, 2-3 years is a common baseline for budget cloth covers, with better-built options (Ravenna, Unicook) reported lasting 5-7 years in some high-trust threads. Sun exposure is the main killer — UV breaks down the coating and causes fading and brittleness — so UV-resistant fabric and shaded storage extend life the most.
