hardly used, never gone off.
The P2-RS is built on a "chassis" of the RS2010 Racesafe body protector, which is approved to BETA 2009 Level 3, with the added protection of Point Two air vest technology incorporated into the garment.
How the P2-RS works
A lanyard attached to the jacket is clipped onto a lead afixed to the horse's saddle. Once the rider leaves the saddle during a fall, the lanyard detaches itself from the P2-RS, triggering the release of CO2 gas from a canister.
The P2-RS will hold a rider tight for 15-20 seconds and then slowly deflate. Rigorous checks have been made on the inflated P2-RS to ensure it did not impede riders should they need to roll away from danger when on the ground.
