When battling a giant rock face for a few days, sleep is mandatory. The Integral Designs 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.
The Integral Designs South Col II Bivy is at home in high exposure. This bivy offers bomber weather protection as well as access and visibility to the task at hand.
