Designed for multi day rafting trips, the NRS River Bed Sleeping Pad lets you sleep like a rock, even if you're sleeping on a rock. The rugged, waterproof PVC exterior sheds moisture and is built to handle all the abuse you can send its way, while the inner polyurethane foam has a medium firm density to protect you while providing pillow soft sleeping comfort. All you have to do is unroll the River Bed, open the valve, and the pad begins to self inflate. But if you're looking for a firmer night's rest, the Leafield C7 valve lets you use your raft pump to inflate the pad for extra cushion. When you're up an at 'em in the morning, two cinch straps with quick release buckles help you roll your sleeping pad compactly for easy transport.
