Troy Lee Designs A2 Helmet MIPSCool, Confident ProtectionBringing style and protection to the trail helmet world, the A2 Helmet MIPS from Troy Lee Designs is a lightweight, protective and highly-ventilated trail helmet for riders who demand comfort and speed without compromise. Troy Lee Designs' dual-density EPP and EPS impact liner absorbs impact forces in both high and low speed crashes and features additional frontal protection. The integrated MIPS(R) technology greatly decreases the rotational forces during an impact, giving you even more protection. Massive intake and exhaust air ports direct airflow over your head to keep you cool, while an X-Static(R) Pure Silver liner wicks away sweat and keeps the funk at bay, letting you ride all day in confident comfort.
