For maximum comfort, the 280 g lightweight helmet is equipped with a 3D IAS adjustment system and 19 generous ventilation openings. Reflective straps enhance visibility. The protective material EPS is directly foamed into the polycarbonate shell, resulting in a lightweight helmet construction with high impact resistance and a perfect fusion of the EPS inner layer and PC outer layer. The uvex IAS system allows for width adjustment of the helmets, as everyone has their own unique head shape. Heads vary not only in circumference but also in height. Therefore, the uvex IAS-3D system offers the additional option for precise adjustment to individual head height. The Fast-Adapting-System strap can be easily and infinitely adjusted to fit the shape of your head. This ensures that the helmet stays securely on your head in all situations, with the strap always in the optimal position. The UVEX Monomatic comfort closure can be adjusted in multiple stages and with just one hand. The closure is twist-proof and features an opening protection in case of a fall.
