Sleeping in a bivy doesn't have to be an uncomfortable experience you'd rather not talk about. Instead, we designed the Backcountry Bivy to fit our revolutionary Backcountry Bed and a 2.5" inflatable pad on the inside of the bivy. Go ahead, sleep how you want - whether on your back, side, or stomach - in a bivy!Accessories Materials Shell Fabric:20d Nylon Ripstop WPB, WR/10,400mm PU WEP, 18,300g/day MVTRFloor Fabric:30d Nylon Ripstop, WR/3,000mm PE, FR Tech Specs Minimum Weight:12.65 oz / .36 kg (Reg) // 14.45 oz / .41 kg (Long)Length:82 in. / 208 cm (Reg) // 88 in. / 224 cm (Long)Shoulder Width:32 in. / 81 cm (Reg) // 36 in. / 91 cm (Long)Foot Width:20 in. / 51 cm (Reg) // 24 in. / 61 cm (Long)Bivy Storage Bag:Length: 9.5 in. / 24.1 cm (Reg) // 10 in. / 25.4 cm (Long)Diameter: 3 in. / 7.6 cm (Reg and Long)
