Super light, super strong, and built with waterproof breathable Todd-Tex fabric, Black Diamond Eldorado is a two-person, single-wall shelter designed for mountaineers and climbers. Able to be pitched on ledges that are no larger than a couch, this is the ideal tent to have at altitude. Its weight is relatively light given its burly construction, yet it rolls up small enough to fit into the side pocket of many internal-frame packs.
