The Helium Active Mobility Panels (A.M.P.) Series PFD blends performance, comfort and flexibility. Constructed of flexible, lightweight, fast-drying neoprene, the A.M.P. vest separates into six buoyant panels with flex channels between each, allowing the panels to move with the wearer as the flex channels change shape freely. The lightweight Ergolite foam conforms to the shape of your body and provides excellent buoyancy. The A.M.P."s unique angled closure allows for all the ease of a standard front zip, while providing the look and performance of a side-entry vest. This Type III personal flotation device is Coast Guard approved.
