Outdoor Research® gear is guaranteed to perform throughout the lifetime of the product.

The Alpine AscentShell™ Bivy is constructed to enable solo adventuring and fast-and-light movements in the mountains and beyond. Building on the reputation set by the cult-classic Alpine Bivy, this new version leverages AscentShell™ x Pertex® technology for a drastically improved breathability rating, leading to less condensation and more comfortable sleep. The step-in opening allows you to step directly into your bed without the need to shimmy into the bivy. Ample headspace makes room for gear; a no-see-um mesh is critical when the bugs are out. The breathable and rugged Alpine AscentShell Bivy is ideal for fast-and-light alpine pursuits or anytime you want to skip the weight and space of a tent.
This Bivy conforms to ASTM Standards. More information can be found here. WARNING: SUFFOCATION HAZARD: Always leave zipper open enough to provide adequate ventilation to prevent suffocation. We recommend at least 6 inches.
