Klim Krios Pro Ventura Helmet The Klim Krios Pro Ventura Helmet introduces superior impact mitigation and enhanced ventilation courtesy of its Koroyd construction. Koroyd's unique material composition offers progressive crush properties, significantly diminishing impact forces, thereby helping to prevent head injuries in the event of a crash. Constructed from a full carbon fiber shell featuring a distinctive wide carbon weave, this helmet not only boasts reduced weight but also maintains robust protection. Equipped with a Pinlock-ready face shield and a Transitions Photochromic lens, it readily adapts to changing lighting conditions, ensuring optimal visibility. Its design incorporates a specifically engineered visor and spoiler to enhance stability at high speeds. Furthermore, the helmet includes a swift, quarter-turn release mechanism enabling easy transitions between street and off-road configurations without requiring tools. When opting to use the helmet without its face shield, the Klim Radius Goggles offer exceptional eye protection, ensuring a versatile and secure experience across various riding environments.
