Protect your digital camera, small valuables and other equipment from the elements with the black 40L Waterproof Dry Tube Bag from OverBoard. Made from 100% waterproof, 600D PVC tarpaulin, this roll-top dry bag has an OverBoard Fold Seal System. Roll the neck tightly 3-4 times to expel all the air and then connect with the plastic snap couplers. When closed, the couplers can also be used as a handle. The bag will float in the water when properly sealed. You can transport it via the heavy-duty grab handle, or the adjustable, removable shoulder strap.
