Packaged singly to be used as a replacement system or for an Eject user with multiple helmets. Eject® Helmet Removal System is a small air bladder that fits easily into any helmet, without changing its fit or feel. In the event of a crash, First Responders can help reduce the risk of secondary neck or spine injuries by inflating the Eject System, which gently lifts the helmet off a rider’s head. Please practice inflation and helmet removal using the reusable practice bladder and Eject Bulb Inflator, which are sold separately.
