Daniel E.wrote a review of Adventure Medical SOL 2-Person Emergency Bivvy on August 21, 2016
Familiarity: I've used it once or twice and have initial impressions
Did the Cirque of the Tower's traverse in the Wind River Range, WY a few weeks ago (mid August) and decided to bivy on a ledge for a few hours until the sun came up. The stars were out and there was little to no wind when we went to sleep, but in less than 2 hours awoke to a snow storm that lasted a good hour and a half. Although we got a bit cold, the SOL bivy definitely saved our asses and allowed us to continue the traverse once it blew over. Very happy with my purchase and will never leave for the mountains again without one. Fit two people comfortably. It did build up quite a bit of condensation from our breath inside the bivy which in turn got parts of our pant legs a little wet and cold. Overall this thing was a life saver.
