The Outrigger is a revolutionary low-profile, rear inflation BC with a patented flow-through High Lift Transfer (HLT) system designed to transfer buoyant lift from the rear bladder to a 15-pound front bladder for effortless face-up surface flotation. Experienced divers agree that a rear inflation design is best for streamlined freedom of movement and positioning underwater, while a jacket style provides more superior surface flotation. Now you can have the best of both worlds.
