Portaledge

A portaledge is a deployable hanging tent system designed for rock climbers who need to spend multiple days and nights on a climbing route suspended from a sheer rock face while big wall climbing. A fully assembled portaledge is a fabric-covered platform surrounded by a metal frame that hangs from a single anchor point via carabiners and has adjustable suspension straps. A separate cover—called a stormfly—covers the entire system to give protection in the event of bad weather. The first portaledges were created for climbing in Yosemite.
