When you need the lightest, most streamlined way to stay dry while you sleep, the Rab Alpine Bivi is one of the best options available. This is Rab’s lightest and most compact bivy, but it’s no lightweight in terms of protection, thanks to the windproof and waterproof 3-layer Pertex Shield Air fabric. Furthermore, the Alpine has a bathtub-style floor, which is inspired by mountaineering tents, giving you extra protection against wet ground. And at less than a pound, even the best ultralight tents can’t touch the protection offered by this exceptional minimalist shelter.

Ultra-Portable | Packing down to just 10” x 5”, this bivi sack will all but disappear in your backpack. Built to Last | Despite weighing less than a pound fully packed, this bivi is rugged enough for regular use by serious adventurers and alpinists. From The Ground Up | Bathtub-style floor with waterproof taped seams keeps you dry even if the ground gets damp. Stay Dry | Waterproof Pertex Shield Air 3-layer fabric blocks wind and rain so you can get some rest. Sleep Anywhere | Rab’s lightest and most compact bivi shelter is ultra-portable while delivering the protection you need in unforgiving mountain environments.
