Product Description
Breathable Premium Technology To Move Quickly In The Mountains
The Alpine AscentShell™ Bivy is the perfect companion for 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™ and Pertex® technologies for a drastically improved breathability rating, leading to less condensation and more comfortable sleep. The step-in opening allows for easy access to sleeping bags without the need to shimmy into the bivy. Ample headspace makes room for gear, and no-see-um mesh is critical when the bugs are out in force.
The breathable and rugged Alpine AscentShell Bivy is ideal for fast-and-light alpine pursuits or skipping the weight and space of a tent.
*Not included: Sleeping bag, pad, and pillows (shown for display only) do not come with your OR Bivy purchase.
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.
