The UK uniBAG is the best bag ever for diving. Use it as a gear bag to haul mask, fins, snorkel, regulator etc. onto the dive boat or to the beach. In the water, the uniBAG folds in-half and snaps together for clipping on your weight belt or BC. A three point strap system allows the bag to be carried as a backpack or slung over one shoulder. The bottom of the bag is made from tough polyester mesh for quick drainage. The upper portion of the bag around the handle is made from polyester fabric so that lobsters, crabs and other spiney game can be shoved into the bag easily without hanging up. An exterior pocket is great for keeping small tools, stringer line, dive light, gloves or the like.
