First off, let me say this BBQ blanket is a game-changer for anyone who takes their meat seriously. The moment I unboxed it, I was impressed by its sturdy waxed canvas exterior—it feels like it could survive a tornado (or at least a rowdy backyard BBQ).

The 21-inch size is no joke. I easily fit a 12-pound brisket with room to spare, and the full-wrap zipper design kept everything snug. Unlike some reviewers who got the smaller 15-inch version, this one truly delivers on its 'large capacity' promise. Pro tip: Always double-check the size before ordering!

Heat retention surprised me. While it's not 100% airtight (you'll notice some air escapes if you squeeze it), my pork shoulder stayed piping hot for 2+ hours—way better than butcher paper. The aluminum lining wipes clean effortlessly, though I wouldn't recommend tossing it in the washing machine.

Where this blanket shines? Outdoor adventures. I've used it for beach cookouts where coolers would be cumbersome, and it kept my smoked turkey warm while doubling as an impromptu picnic blanket. The handles make transport a breeze.

Two minor gripes: The paper-bag-like exterior had me worried about durability at first, but after 6 months of use (including a camping trip where it got rained on), it's held up remarkably well. Also, while it works for cold foods, I'd stick to insulated bags for true refrigeration needs.

Final verdict: If you frequently host BBQ parties or love tailgating, this is worth every penny. Just make sure you're buying the 21-inch version—the 15-inch seems to disappoint based on other reviews. My brisket has never been juicier!
