THE OUTDOOR RESEARCH ALPINE ASCENTSHELL BIVY. YOUR SHELTER FOR THE HARDEST CONDITIONS.

Alpine protection and all-night comfort, minus the weight. With the lightweight durability of Pertex® and breathable, waterproof AscentShell™ technology, this solo shelter is faster, lighter, and ready for every adventure.

Solo adventuring just became effortless. Building on the legacy of the iconic Alpine Bivy, this new version takes things up a notch with AscentShell™ x Pertex® for exceptional breathability. Say goodbye to condensation and hello to a more comfortable sleep. The step-in opening lets you slip out of your boots and into bed without the hassle, while the generous headspace gives you room for your gear. The no-see-um mesh keeps the bugs at bay. Perfect for alpine pursuits, extreme weather, or anytime you want to leave the tent behind and go lighter, faster, and more efficiently.
