Strikingly elegant and dynamic, the MET Estro Road Helmet has streamlined lateral lines and combines an aerodynamic front with a full wrap rear cradle to give you a wind-cheating advantage. In-Mold Intelligent Fusion construction uses different densities of materials that provide confidence without added weight or volume. 20 large openings provide excellent flow-through ventilation and internal Cocoon padding relieves pressure points while adding comfort. Kevlar straps and Strong-Fit dividers are lightweight, tough and securely anchored, so you can customize the fit. Safe-T Advanced retention system goes around the whole circumference of the head and allows the helmet to rotate very slightly in the event of an impact for better shock absorption and dissipation.
