For camping, survival or just running the rapids for kicks, the Uncharted Rapid Raft is the world’s lightest pack raft. It weighs less than 3 pounds, inflates in seconds and holds 400 pounds. Packed down, it’s the size of a loaf of bread, so definitely light enough to fit in your pack. And it’s made of nylon TPU, so it’s rugged enough to withstand river bottoms, rocks, & debris. Inflates in 3-seconds with no pump or tools needed. A funded Indiegogo.
