The groundbreaking A2 MIPS® is the Troy Lee Designs MTB trail helmet that meets all requirements. The stylish shell not only features large intake and exhaust vents but also offers the best impact protection. From breakaway visor screws, the innovative MIPS® system, and an industry-leading Dual Density EPP + EPS inner shell that protects against both high and low-speed impacts, the A2 is a helmet that takes your safety seriously. Add a redesigned adjustable strap and X-Static® Pure Silver comfort helmet pads, and the comfort is matched to the protection in every way. MIPS® - Multi-Directional Impact Protection System is the industry-leading protection against angled impacts. The industry's first Dual Density EPP + EPS helmet inner shell provides top-level protection against both high and low-speed impacts. A 16% thicker EPP + EPS helmet inner shell in the frontal area compared to the A1 increases protection in typical impact zones. Innovative breakaway visor screws reduce the likelihood of snagging or catching in an accident. Massive intake and exhaust openings deliver maximum cooling performance with more than 25% higher airflow compared to the A1. Brand new, flat semi-adjustable strap dividers offer the perfect fit regardless of head shape. Exceeds certifications: CPSC 1203, CE EN 1078, AS/NZS 2063.
