USCG Approved Flotation. The aquatic version of the the Retriever is accentuated by the inclusion of USCG approved foam flotation that is stored integrally in unique mesh pouches of the Retriever. No time is lost in placement of flotation, again saving time and training effort. The foam is unicellular, unable to absorb water, and vinyl coated for ease of cleaning. The amount of foam meets or exceeds international commercial flotation requirements, and provides positive head and chest buoyancy.
