The Alpinestars Bionic Neck Support (BNS) Tech-2 incorporates a bio-organic engineering design for superb ergonomics. Rear stabilizer promotes PFR (Progressive Force Relief) and dissipate energy loads by transmitting them across the back and shoulders and away from spine (thoracic vertebrae), and is connected to the frames via pivot key. Frame construction promotes improved contact with helmet during impact – including rear support edge that fits closer to the body, extra width to account for different helmet sizes and raised chest to reduce hyper-flexion. Innovative quick-release locking system for rapid and efficient fitting/removal offers highly secure and convenient closure. Compressed EVA foam compound padding to distribute the impact force over the widest area, yet remain lightweight.
