Sea To Summit Big River Dry Backpack Let's Get Wet and Wild! The Big River Dry Backpack is built to be around water, keeping your gear safe so you won't have to stress about soggy items when you get to camp. It's comfortable to carry with adjustable shoulder, sternum, and hip straps to keep your load stable through choppy currents. Its simple design makes it easy to lock out the elements but it is incredibly durable with protection from punctures, abrasions, and water. Simply roll the closure until it's airtight, then use the buckles to cinch it even more, with double-stitched, waterproof seams that take care of the rest. Note that it is not meant to be fully submerged, but it is ideal for paddle sports or moto-touring so you can kayak, pack raft, canoe, or tackle whitewater rapids without worrying about your belongings.
