The Osprey Vest and Aviation Life Preserver is FAA Approved under TSO-C13G.  Unique to the LPFC is the use of the mini-buckle attachment system permitting easy installation of the collar and allows the flexibility to dress for land or over-water missions. The portion of the collar that lies across the shoulders is only ¼” thick, eliminating interference with helmets common with other collars. Collar can be quickly replaced if damaged or removed for inspection. Buckles have been revised to provide a secure, tight fit between the collar and vest, eliminating slack and unwanted collar movement, while ensuring optimal in-water flotation performance by keeping the inflated collar close & tight to the body.
