Built from the recommendations, feedback, and favorites of Outdoor Research employees, the Interstellar Bivy represents years of idealizing the perfect night spent outside. Seam-taped AscentShell technology delivers waterproof breathability, and a single pole can be used to add headspace or left at the trailhead to save weight. A newly designed side entry makes getting in and out of your shelter faster and easier than ever before, while innovative zipper design and built-in sombrero allow you to sit up and perform tasks (like cooking and packing) without stepping outside.
