Stargazer Bivy

Compared to all of Outdoor Research's bivies, the Stargazer Bivy boasts better breathability, reliable waterproofing, and a larger mesh screen for alpinists and backpackers who prefer a view as they snooze. 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.
