Giro Cinder MIPS Helmet Medium Matte Black Fade/Highlight YellowThe Giro Cinder MIPS Helmet is built for speed and safety: it’s built from Polycarbonate Construction with an EPS Liner (plus a Thermoformed SL Roll Cage reinforcement), making it both lightweight and structurally sound. The Multi-Directional Impact Protection System (MIPS) technology is designed to keep you safe by mitigating dangerous rotational forces during certain impacts while you’re cycling. There are 26 Wind Tunnel vents with internal channeling to keep you cool naturally, and the Roc Loc 5 fit system allows adjustment of the vertical position and fit tension with just one hand. The interior of this helmet is cushioned with Air-FX padding for a soft fit—but it’s still ponytail compatible. Available in Small, Medium, and Large Sizes. Small: 20-21.75’’ (51-55cm). Medium: 21.75-23.25’’ (55-59cm). Large: 23.25-24.75’’ (59-63cm). Available in Black Fade/Highlight Yellow, Matte Black/Charcoal, and Matte White.768686376009
