Designed for professional alpinists and serious adventurers, the Pro Bivy delivers quick-pitch protection in cramped spaces too small for a tent. Lightweight to keep up with fast & light missions, whether you're traversing the rugged Pickets Range or fastpacking the Wonderland Trail, the Pro Bivy features weatherproof, breathable fabric that reduces condensation, and Xtreme Shield waterproof coating to help keep you dry and comfortable on your alpine challenge.
