Using the same inflatable bladder from our best-selling Fluid 2.0, the SUP Safety Belt packs down smaller to give you peace of mind in a compact package. The smallest US Coast Guard Type III belt pack PFD, the SUP Safety Belt is approved to be worn or carried - perfect for SUP yoga practitioners. Side buckle makes it easy to put on and adjust for a snug fit, and neoprene liner is soft against bare skin.
