Product Reviews
Rated 4 out of 5 by from Great Features in This Bag I'm a side sleeper so this for sure caught my attention. I haven't used it out on the trail yet but from testing around the house, it appears to be a great buy. Super comfy, nice and light, feels very warm and just a quality overall product. The only knock from a 5-star review right now is it does feel a bit snug. Wish I had a little more room around the shoulders. I am not a overly big guy, just a little thicker than the average 5'8" male.

Rated 4 out of 5 by from Comfortable but not for colder temps The bag was comfortable, but temps got down to 31 degrees and could not stay warm. My sleeping pad is an r value of 7 so I stayed warm underneath but froze on top. They say it’s a snap free zipper but is surely not. Snagged far too many times for me. I returned this bag.

Rated 5 out of 5 by from Kept me nice and toasty I finally got out camping this past weekend in the Rocky Mountain National Park. Overnight lows were 32 degrees. I did also use a sleeping bag liner because I was afraid I might be cold. But I was very comfortable all night long. I actually stayed in the tent from 9PM to 9AM.

Rated 4 out of 5 by from Great side sleeper, wish for a lighter version Comfy, warm, great as a side sleeper, just wish there was a lighter version available. Pretty easy to get in and out of, although the zipper can be a little fussy.

Rated 4 out of 5 by from Features & Sizing are great This bag has gone on 2 weekend backpackers and a 1 week campground excursion so far. It has been leaking more feathers than expected... Feature specifics: -Pillow "barn" works well, little hard to fit a larger pillow into it though. Takes a little getting used to to find the hand pass-thru and move the pillow - Zipper - pretty good, does catch up occasionally but that's expected - Hood cinch/draft - works great! The footbox design is the best part of this for side sleepers. The dimensions are perfect.
