Great protection, huge vents and European styling combine to form the Mavic Plasma SLR Helmet. Seven oversized vents up front and on the sides, and nine exit vents in the rear provide unrivaled ventilation and airflow. Mavic was able to achieve this by using carbon fiber structural reinforcement, allowing for oversized vents with no compromise on protection. Mavic's unique head cradle, Ergo Hold, provides secure and easy one-hand adjustment for the perfect fit, while the Ergo Fit Pro Pads with X-Static ensures sweat wicking capabilities and moisture management with anti-bacterial protection. The aggressive, low volume and aerodynamic shape channels cooling air into the helmet and delivers the fast, sleek and stylish design you want. Reflective highlights aid in being seen and the helmet includes a convenient carrying bag. 285 grams (med). SM (51-56cm), MD (54cm-59cm) or LG (57-61cm).
