CSU-17/P Anti-G Vest is part of the Combat Edge pilot system to increase crewmember tolerances to G-Forces, letting them turn tighter than the enemy and hold a turn longer to gain the advantage. The CSU-17/P is a vest that does the same job as the G-pants- by filling with air as G-loading increases, it places pressure on the wearer's body to keep blood from pooling in the extremities. We have these vests in excellent and good condition. The good condition vests may have some corrosion on the zippers and possibly be stuck or may be marked "training use only". Each CSU-17/P comes complete with hose and 4 pin connector at the end of the hose to allow the vest to be connected to the CRU-94 oxygen block. Please choose size, and condition.
