SaS Tec amour offers the best possible protection during a dynamic impact. The armour is made of a new polyurethane foam material, without a hard shell or edges which surpasses the required CE- values by 50%. The closed air cells function by means of progressive absorbtion: with a slowly occurring stressor, the material remains soft and flexible, whereas sudden impact will cause the protector’s air cells to respond quickly with increased resilience, creating a protective shield where the rider needs it most.
