When battling a giant rock face for a few days, sleep is mandatory. The Rab Andes South Col II Bivy lets you hunker down for some shut-eye while out on a ledge. Its venting armholes enable comfort once you zip up the center water-resistant zipper, and a weatherproof tie-in hole keeps you anchored if the storm blows in overnight. Weighing in at just over a pound, this bivy provides overnight protection with minimal weight for big-wall climbing or mountaineering.
