Always in development. With a design and materials used in aerospace engineering, we managed to bring the D4 Composite helmet down to 1050 grams without compromising strength. The Mips® C2 protection system provides an additional layer of safety in the event of a fall. Comfort is ensured by the D4 Composite with an airflow system that channels cool air through a front air inlet, through the polymer center, and the Power-Grid side mesh to keep the head cooler during rides. X-static® and XT2® antibacterial/anti-odor padding ensures that the inside of the helmet remains a significantly more pleasant place.
