Enduro mountain biking requires versatility. Once the uphill section has been mastered and the knee protectors have been adjusted, the uvex jakkyl hde is ready to go. The removable chinguard can be fitted in just one easy step. The half shell becomes a full-fledged full-face helmet in a fraction of a second. Open the shock absorber, give the pedals a good push and you're off downhill at top speed. At the same time, 14 ventilation openings with fly net regulate the helmet climate. The size is adjusted via the proven Anatomic IAS system. Clever: A goggle can be parked under the adjustable visor. A goggle strap holder is on board for a secure hold on rough trails. The width of the helmet can be adjusted with the uvex IAS system. After all, everyone has their own individual head. However, heads differ not only in their circumference, but also in their height. The uvex monomatic comfort closure can be opened and closed with one hand. The Fast-Adapting-System harness can be easily and continuously adjusted to the exact shape of your head. This keeps the helmet firmly on the head in all situations and the strap always in the optimum position. The EPS protective material is foamed directly into the polycarbonate shell: for a lightweight helmet construction with maximum impact resistance and the perfect fusion of EPS inner layer and PC outer layer.
