The Foray drafts off the bold design language of Giro's premium Synthe helmet, and offers many of theirkey features including durable in-mold construction and the Roc Loc® 5 fit system with two-way fit adjustment. The slim design is very light, offers great ventilation and is available in three Super Fit sizes so that you can get a helmet that looks, fits and feels like it was made for you. MIPS models are available with the Multi-Directional Impact Protection System. We believe MIPS can redirect energy and provide more protection in certain impacts.Features:Streamlined Design, Plush interior, MIPS equippedConstruction:In-mold polycarbonate shell with EPS LinerFit System:Roc Loc 5Ventilation:21 VentsSIZINGS: 51-55cmM: 55-59cmL: 59-63cm
