The Fishpond Castaway Roll-Top Gear Bag was designed to keep valuable gear dry thanks to its water-tight closure. This bag is constructed of TPU welded fabric and 420-denier recycled nylon. The molded bottom helps keep the bag in place on boats. The Castaway Roll-Top Gear Bag will fit most flat boat hatches and could also be used on rafts and drift boats. The roll top feature keeps your gear dry when you’re out on the rapids. The Fishpond Castaway Roll-Top Gear Bag can be packed flat for travel thanks to the removable padded interior.
