The Helite Turtle Airbag Vest offers the highest level of rider safety. The lightweight vest protects riders' spine and vital organs due to its revolutionary design, inorporating a back protector on top of the air bag that disperses impact forces across the vest instead of concentrated in one spot. With its mechanical trigger and lead system, there are no delicate sensors to fail or batteries to replace. Simply connect the lead to your vest and bike and go. When the rider is ejected from the motorcycle in the event of a accident, the trigger is pulled and the vest inflates, creating a rigid neck brace as well as firm support to the spine, back, chest, ribs and kidneys.
