Features Lightweight thermoplastic helmet Thanks to the many hours devoted to aerodynamics studies and wind tunnel testing, the SX.100 s special shape allows for a relatively lightweight helmet with a sporty design that optimizes both stability and high-speed sound insulation. Comfortable fit & Ventilation and air supply The 3D molded lining is fully removable and washable, sweat-resistant and anti-allergic. The thick neck roll is also removable and washable and prevents air from entering under the helmet. Excellent eye-opening The SX.100 eye-opening is particularly wide and offers a heightened sense of openness in the helmet interior, a sense of freedom, ideal for all urban conditions. The visor is scratch resistant and designed for use with a mist-free Pinlock disc.
