The Imperial 160RT Basic Ferry Boat personal flotation device (PFD) is an inherently-buoyant, self-righting lifejacket designed to be worn by an adult for extended survival in rough, open water where superior flotation characteristics are necessary. The 160RT is available as an individual unit, or packed as a set of four in a 22"L x 12"W x 13"H hassock bag. A smaller size is also available for children.
