Louis Garneau 2006 OZ-ZY Helmet

"Everything you could possibly want in a helmet: sixteen huge vents to provide an incredible amount of airflow, a SpiderLock 2 retention system that grips like Velcro and a durable, clean look of In-Mold construction. All this creates the helmet that provides as much protection as it does second looks. Sizing: S(21 1/4"- 22), M(22-22 3/4"), L(22 3/4" ? 23 5/8")."
