During the design process, we focussed on three key performance principles: Fit. Breathability. Value. Fit and breathability are ensured by the Ventilated DH Air padding and the Ionic+ antimicrobial comfort lining, which uses silver metallised yarns to control odour in the helmet. The helmet is equipped with 14 vents to optimise ventilation and a Fidlock buckle for easy, one-handed opening. The in-built Mips system reduces rotational forces in the event of a fall. The Sanction II is also ASTM-certified for downhill and BMX.
