Constructed from fiberglass resin with interchangeable EVA foam pads, Alpinestars' BNS Pro Neck Support minimizes risk of serious injury. During a crash, the BNS Pro's structural integrity, from the lightweight resin, protects against heavy impacts. At the rear of the BNS Pro, a rear stabilizer promotes PFR Progressive Force Relief to dissipate energy loads across the back and shoulders and away from the vertebrae. The frame design also promotes improved helmet contact through a wide support edge, which accounts for varying helmet shapes and sizes to reduce hyper flexion. The fiberglass frame isn't just light and tough, Alpinestar also designed it with superb ergonomics. This not only improves comfort when riding, but it includes an innovative quick release locking system. The result is speedy and efficient fittingremoval for simple gearing up or post ride gearing down. EVA foam padding distributes impact forces to reduce injury and to cushion. Alpinestars' BNS Pro Neck Support comes in the color Blackwhitered and in the sizes X Smallsmallmedium and Largex large.
