30 ° Schroth carbon collar for the HANS system. Available in two sizes M and L. Schroth HANS (Head And Neck Support) collars are of the highest quality and safety. The product has Vision Advantage Plus technology, which allows the user to make virtually unrestricted head movements. In addition, the collar is equipped with "graters" of the SlipStop system, which prevent the seat belts from sliding off the collar, which can be dangerous in the event of an accident. The HANS system is mandatory in all racing and rally cycles organized by the FIA and in an increasing number of national and international series . In the event of an accident, the HANS collar absorbs more than 80% of the forces acting on the neck in a frontal impact against a fixed obstacle.
