Hit-Air vests are designed to be super-light weight and flexible - for ultimate comfort and freedom of movement, while providing optimal protection on inflation. The award winning air bag is triggered when the rider and horse become seperated to provide a stabalising, shock buffering system for added protection to the neck, spine, chest, ribcage, lower back and vital organs. The current offer includes the vest, saddle strap, lanyard and full instructions which you must read carefully before using your Hit-Air vest. This option requires a 48CC canister.
