Outdoor Research Alpine AscentShell Bivy – Nimbus

Experience alpine protection and all-night comfort without the weight when using the Alpine AscentShell Bivy from Outdoor Research. Leveraging AscentShell™ x Pertex® technology, its high breathability rating means less condensation and a more comfortable sleep. Its step-in opening allows you to step directly out of your boots and into your bed 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 come out. 

This bivy is ideal for alpine adventures, extreme weather, or anytime you want to skip the weight and space of a tent.
