The Bionic Neck Support Tech 2 is constructed from a high-performance advanced carbon polymer composite and is designed to help prevent injuries in a collision situation by dissipating and deflecting impact forces from the neck and spine. Bionic Neck Support works when the rider's helmet makes contact with the structure during a collision, thus providing a clean, solid surface that instantly channels damaging compressive impact energy away from the neck and into the BNS. Featuring Alpinestars' unique and revolutionary Rear Stabilizer for Progressive Force Relief (PFR), the BNS Tech 2 is designed for use on motocross and off-road riding and offers a highly customized and stable fit, while incorporating innovative new features , as a new quick release lock system.
