Outdoor Research Alpine AscentShell Bivy

Solo adventuring just got a whole lot more comfortable and convenient. Building on the reputation set by the cult-classic Alpine Bivy, this new version leverages AscentShell x Pertex technology for a drastically improved breathability rating which leads to less condensation and a more comfortable sleep. Its step-in opening allows you step directly out of your boots and into your bed easier and without the fuss of shimmying. Extra large head space makes room for gear, and a no-see-um mesh comes in handy when the bugs are out for blood. This bivy is ideal for alpine pursuits, extreme weather, or anytime you want to skip the weight and space of a tent.
