The Troy Lee Designs A2 MIPS® MTB Trail Helmet is designed to exceed your expectations in terms of safety, comfort, and ventilation. Compared to the TLD A1 helmet, the dual-density EPP + EPS inner shell has been reinforced by 16% to provide even better protection against impacts at both low and high speeds in typical impact zones. The MIPS® safety system also reduces rotational forces on the head in the event of an angled impact. Additionally, in the event of a crash, the visor screws break off to minimize the risk of snagging. Massive intake and exhaust vents ensure maximum cooling with over 25% higher airflow compared to the A1 model. The flat, semi-adjustable strap dividers and the X-Static® Pure Silver comfort helmet padding offer the biker a perfect fit and the highest wearing comfort, regardless of head shape. Outer shell: 100% polycarbonate. Inner shell: 65% expanded polystyrene (EPS), 35% expanded polypropylene (EPP). Lining: 95% polyester, 5% elastane. Exceeds certifications: CPSC 1203, CE EN 1078, AS / NZS 2063.
