Great bag, but zipper snags a LOT.
3 weeks ago
VERY warm bag. Waiting for the sun zero temps here in Alaska to really put it to the test, and will update my review after that. I got inside it in my living room and was sweating within a minute. I’m only leaving a “first impressions” review because of the zipper. It gets snagged A LOT. More than any bag I’ve had yet. I wish there was something in the design to reduce the zipper snagging. Otherwise, I’ll update with my other findings once the show flies and I go on some extreme winter camping trips!
