Alliance Threshold Motorcycle Helmet Silver

Alliance Threshold Motorcycle Helmet Silver
The Icon Alliance Motorcycle Helmet is fitted with a multitude of key refinements. The first revision is the new EPS liner. We�ve listened to the customers requests and reshaped the EPS liner into a more oval geometry. This new head form increases rider comfort by slightly elongating the entire inner circumference. Combine this geometry with our removable Hydra-Dry� wicking comfort liner and the result is a nearly perfect rider focused enclosure. To further increase rider comfort we�ve revised the entire venting system. Much like a finely tuned motor, we�ve reshaped and enlarged the intake and exhaust ports for increased airflow in the Icon Alliance Motorcycle Helmet. Injection molded polycarbonate shell for strength. Long oval head form. Wind tunnel tested and refined. Molded twin channel super vent for increased cooling. Rear exhaust ports prevent heat buildup. Removable molded breath deflector reduces shield fogging. Chin venting system reduces shield fogging. Full removable/washable Hydra-Dry� interior. Quick-change fog-free Proshield� with side plates. Prolock� shield locking system. Meets or exceeds the following: DOT FMVSS 218 (US), ECE 22-05 (Europe). For proper fit and size measure the circumference of your head 1 above your eyebrows and around the largest portion of the back of your head. 20 7/8 - 21 1/4 ----X-Small 21 5/8 - 22 --------Small 22 3/8 - 22 3/4 ----Medium 23 1/8 - 23 1/2 ----Large 24 - 24 3/8 --------X-Large 24 3/4 - 25 1/8 ----XX-Large
