Mustang Survival's new line of Deluxe Inflatable PFDs took all the best features of the original AirForce PFDs and integrated additional advanced safety technologies. These great new features include a compact design that lays flat against your chest to provide maximum mobility. A neoprene collar provides comfort, and the 420-denier nylon provides durability - the best of both worlds. Unique to the Mustang Deluxe PFD is an at-a-glance inflator inspection window. Green indicates the Halkey Roberts Pro 1F Auto CO-2 inflator is ready to use. This PFD will provide up to 35 lbs. of buoyancy when inflated and is capable of righting most wearers face up. A back-up oral inflation tube is also provided as is a safety whistle to alert rescuers. USCG approved.
