Klymit LiteWater Dinghy

It's a boat that fits in a backpack: the LiteWater Dinghy by Klymit, a one-person inflatable pack raft that packs down to 9 x 4.5" and weighs just over 2 lb. Class 2 rated for calm or wavy water with easily avoided obstacles, the raft has a capacity of 350 lb and six tie-down points for your gear. Inflated, it measures 76 x 45", with internal dimensions of 41 x 18". Its stuff sack doubles as an inflation bellows. Two inflation/deflation valves are provided for quick setup. The seat inflates separately for extra comfort and insulation from the water.
