Kevin R. ★★★★★ Aug 22, 2026

The mummy cut hugs just right without feeling restrictive, and at this weight I barely notice it in my pack. Slept warm down to freezing on a ridge line, and the zipper never snagged once during the whole weekend.

Mia D. ★★★★★ Aug 21, 2026

Took this out on a three-day trip and the mummy fit kept me cozy down to freezing without adding much bulk to my pack. The sustainable build is a nice bonus, and it's light enough that I barely noticed it strapped to my bag.

The zipper glides without snagging even when I'm half-asleep, and the mummy cut keeps me tucked in tight on chilly nights. It's light enough that my pack didn't feel like a brick on the trail, so I'm happy with the trade-off for the warmth.
