The primary difference between a regular PFD and a rescue PFD is the inclusion of a Quick Release Harness Belt System (QRHS). Designed for experienced paddlers who may need to perform swimming rescues, the Patriot QRHS meets new UL/USCG standards. Like the Big Buoy, the Patriot is a high buoyancy jacket, yet offers an extremely comfortable fit. Two large neoprene pockets for quick access to items like GPS or VHF. 5 points of adjustment. 500 D Cordura® shell.
