I’m a bigger guy and usually dread squeezing into mummy bags, but the extra room here is a game changer—I actually slept with my arms crossed without feeling trapped. The fabric feels tough enough for years of car camping trips, so it’s already earned its spot in my gear closet.

The zipper glides so smoothly that it’s almost a treat to crawl in after a chilly hike. The extra room means I can actually turn over without wrestling the fabric, and it still feels plenty warm when the temps dip near freezing.

I'm a bigger guy and always struggle with mummy bags feeling like straightjackets, but this XXL cut finally gives my shoulders and feet room to move without waking up tangled. Even at 20 degrees with just a base layer, I stayed toasty all night long on last weekend's trip.
