Every few years a product hits the shelf that turns the off-road industry on its head. Leatt has done just that with their revolutionary Leatt Moto GPX Club neck brace. The Leatt Moto GPX Club neck brace was designed to prevent these extreme movements of the rider's neck in the event of a crash: hyper flexion, hyper extension, lateral hyper flexion, axial loading, and posterior hyper translation. The Leatt Moto GPX Club neck brace was designed to re-direct the helmet in the event of a crash so that the brace absorbs and re-directs that energy in a safe manner instead of the neck taking the majority of the impact which could result in a serious injury. Designed by medical professionals with the motorcycle enthusiast in mind. The glass-reinforced nylon fiber and Kevlar body was shaped in a way as to not effect the riders mobility or visibility. With the use of glass-reinforced nylon fiber and Kevlar Leatt was able to create a brace strong enough to absorb significant impacts and stay light at 850 gram so that the rider did not experience fatigue while using the brace on their motorcycle or ATV. Sizing Guideline: Small: 4-16 years old (thin build) Medium: 16 years + (average to bigger build)
