Outdoor Research AscentShell Bivy
When the alpine forecast whispers of an abrupt shift, or the call of a remote ridge demands a minimalist overnight, Outdoor Research's AscentShell Bivy answers with confident protection. Engineered with groundbreaking 3-layer AscentShell technology, this shelter actively breathes, expelling internal moisture vapor at an astonishing rate while forming an impenetrable barrier against wind-driven rain. Weighing a mere 15.6 ounces and packing down to the size of a water bottle, it’s the ultimate featherlight sanctuary for fast-and-light traverses and unexpected bivies. The innovative internal pole creates a welcome pocket of overhead space, preventing the fabric from collapsing and allowing for comfortable ventilation through the generous no-see-um mesh screen, ensuring restless nights due to condensation or critters are a thing of the past. Coupled with a robust 40D nylon floor featuring a high-traction anti-fungal finish, this bivy offers resilient durability and peace of mind, empowering you to embrace the wild without compromise, confident in your ultimate, compact refuge.
