    Interstellar Bivy

    The Outdoor Research Interstellar Bivy combines enhanced breathability with exceptional waterproofing worthy of four-season adventures whether you're backpacking minimally in the summertime or mountaineering in wintertime. Its waterproof Ascentshell membrane is air permeable instead of breathable, meaning it will breathe the moment you enter the bivy, as opposed to standard breathable membranes that only breathe until after you build up moisture with breathing or sweating. The Delrin single-pole system is quick and easy to set up, and you can leave it at home if you want to save some weight and packing space.

    • Four-season bivy for alpinists, backpackers, and winter campers
    • Ascentshell is waterproof and air permeable for high breathability
    • Multi-configuration lets you sit up an organize gear in bivy
    • Delrin single-pole system, guy line loop, and two stakes for setup
    • Item #ODR00X4

    Sweet New Take On A Classic

      I've really enjoyed using the Interstellar Bivy. It kept me dry and happy in some pretty challenging conditions, and the features are above and beyond what you would normally see in a bivy. While bivies aren’t for everyone, this is a great alternative to a tent for someone who wants a light and fast to set up sleeping option. It’s versatile enough to perform in a variety of conditions and is much easier to set up than a tent.
