The Ravel loves gravel. The dynamic bridges indicate the direction of travel: it's going forward. And when it gets fast, the gaps provide good ventilation. If the gravel path is rough, the helmet should fit well. Additionally, the gravel helmet is safe, lightweight, and comfortable to wear thanks to Inmold-Tec manufacturing. An antibacterial interior ensures that it stays that way. Optionally, the Ravel can be equipped with a flash light.
