The Sierra Designs Backcountry Bivy is a big bivy sack that is large enough to hold a thick air mattress and a cold-weather sleeping bag.
Still designed to fit our revolutionary Backcountry Bed and a 2.5” inflatable pad on the inside of the bivy, so you can sleep as comfortably on a rock ledge, as you do at home.
