Abigail ★★★★★

I love that I can unzip the side and turn it into a quasi-quilt on warmer nights, then cinch it back up when the temperature drops. Perfect for those unpredictable

Carter Z. ★★★★★

Slept warm and comfortable down to around 40F, and I really like that you can unzip the sides to make it wider when it's hot. The adjustable shape actually makes a difference — I opened it up on the warmer nights and cinched it down when it dropped.

Isabella ★★★★★

The adjustable shape is what sold me — I can cinch it loose when it's mild and snug it up when the temp drops. Stayed toasty right around freezing without feeling clammy. Best sleep I've gotten on the trail in years.
