This is a Mares BCD Hybrid. It folds in half for easier packing, especially useful for shore diving. It comes with an Air 2 type inflation hose by Mares. It is an XL size. I generally travel to warmer waters, so I am trying to travel light. This is not an overly heavy BCD. It is backpack type of buoyancy bladders and (this is a plus for me) also fills the sides with air, very stable. It is in top notch condition, I just replaced the collar system. It has integrated weight pouches (no weight belts) and trim pouches in the rear. It also has an AIR 2 type of alternate air / inflation hose (cleans up the number of hoses hanging about) $250. I can also ship this as well..
