What denier fabric should I look for in a grill cover?

Specialist subreddit discussions in r/grilling consistently flag 600D polyester or Oxford fabric as the practical sweet spot for durability without becoming unwieldy. Heavier 900D or 1200D covers exist but reviewers note diminishing returns and harder handling. Marketing claims of high denier are common, so cross-check against verified-purchase reviewers who comment on hand-feel and tear resistance after a season outdoors.
