LSI Product ID: flo-4565-00

AID Model: MSV971

Designed specifically for pilots and aircrew to be worn over flight suits, the MSV971 is an inflatable cell integrated into a survival vest.  Providing a full 37 lbs of buoyancy, the inflatable cell - available in manual inflation - is comprised of two independent chambers separated by a fully integrated floating baffle system.  This provides for an orally inflated reserve chamber in the event that the primary chamber becomes damaged.

Each vest is lightweight - approximately 3 lbs unloaded - and contains specific pocket requirements for stowage of survival items such as rations or lights.  It is made with a Nomex fire resistant cover and mesh for high durability.  As well, each vest is integrated with a lifting harness for over water rescue by helicopter, and contains a buddy line and SOLAS emergency whistle.
