Worn comfortably around waist. Quick and reliable manual CO2 inflation by pulling lanyard or by oral inflation tube. Heavy-duty adjustable waist belt and torso slide straps for a custom fit. Provides minimum of 32 lbs. of buoyancy when fully inflated. USCG approved, Type V with Type III performance. I prefer to fly with this PFD. Its small, lightweight, and it can stay in the pack until the escape is complete.
