2009 Ionos Road Helmet

21 Large Wind Tunnel vents with internal channels push 15pct more cool, fresh air over and around your head while forcing heat and stale air out. In-Mold construction provides strength, integrity and is so lightweight, it virtually disappears when you put it on. In-Mold Composite Sub Frame is tuned to deliver incredible structural support, impact dispersion and resistance to penetration (and it"s the secret to the Ionos" ability to offer great big vents without compromising protective capability). Impact absorbing X-Static padding gives you comfortable cushioning. Fully adjustable, Roc Loc 4 retention system aligns the helmet"s fit tension and vertical position for a truly custom fit.
