I would sleep in it again and again and again


I spent a couple of winter nights in while in the forests of Northern Arizona. The bivy kept me warm and dry in the snow. When sleeping that first night outside, I always end up tossing and turning, the bivy was nice and roomy to let me move around (I'm 5'9" and wear a L jacket). The only thing I don't like are the fifty-thousand (i kid) zipper pulls. Granted they're all labeled, but at 2 in the morning, I'm not looking to read the label.

Warm and Comfortable in Below Freezing Conditions


I was not a bivy user before committing to try the Interstellar Bivy. I have been backpacking for years and was a committed tent user. I had written off bivy sacks as constricting, limited, and tricky to use. I was wrong and I'm now a converted bivy user. I used the Interstellar on a below freezing night outside of Zion National Park. My sleep system included the bivy, and R 5.7 sleeping pad, and a 20 degree quilt. After some initial fiddling with zippers I settled in warm and cozy. I had just enough room to read and plenty of room to shift positions. (I am a restless sleeper) I slept warm and comfortable through the night. This is in contrast to the four other people in my group - one with a zero degree bag - that reported being cold. Bivy sack for the win! I will be modifying this to add longer parachute cord zipper pulls to the main zipper vs. the hands zipper. They are all the same size and can be otherwise confusing. Easy fix.
