Superior Waterproofing: The roll-top seal ensures reliable watertightness, convenient and practical. You simply open the bag to let in as much air as possible, then roll the top down 3 to 5 times and clip the ends together. This keeps air in bag, prevents water from seeping in and allows bag to float. As long as the bag is not completely submerged, whether in rapids or other wet situations, it flawlessly keeps the contents dry, protecting them from water, snow and sand.
