Light in weight but not light in features. The new SingleTrack Helmet incorporates Koroyd® panels in high impact areas to provide increased energy absorption. It also features the MIPS® Brain Protection System, designed to reduce rotational motion transferred to the brain from angled impacts to the head. Koroyd® 3D formed inserts enhance airflow and improve energy absorption in an incredibly lightweight package, making it one of the most breathable and lightweight helmets on the market while offering superior impact protection over standard construction. Designed with airflow in mind, the large vents maintain a linear flow of air to maximize breathability and comfort. The helmet is covered by Endura’s Crash Replacement Policy and Product Guarantee. Certified to CPSC and CE EN1078:2012 + A1:2012 Standards. Construction: Main Polystyrene 50%, Polycarbonate 25%, Polypropylene 15%, Nylon 5%, Polyester 5%.
