The Alpine AscentShell Bivy by Outdoor Research is a new and improved version of the famed Alpine Bivy featuring more breathability for less condensation and more comfort. When you’re high in the mountains, weight, protection, and comfort are key elements when choosing a shelter. The Alpine AscentShell Bivy is ultra-lightweight coming in at just 1 lb 2.6 oz with the pole included. Lightweight bluesign approved AscentShell x Pertex Shield Air Diamond Fuse fabric is highly breathable, completely waterproof, and fully seam-taped for the weather protection needed for alpine hunts. The durable 40D nylon floor is TPU laminated to protect you and your gear from harsh ground and weather. The large side opening makes it easy to step out of your boots and into your sleeping bag and the added headroom provides some space for small accessories such as a phone, headlamp, gloves, and anything else you may need throughout the night. The extra-large mesh screen is great for stargazing on calm nights and will keep the bugs from feasting on you all night.
