The Troy Lee Designs A3 MIPS Helmet represents the pinnacle of trail and all-mountain protection, combining advanced safety technologies with exceptional comfort, ventilation, and fit. Designed for riders who push their limits on every ride, the A3 delivers premium performance whether you’re climbing technical singletrack, charging descents, or spending long days in the saddle.
Built around a co-molded EPP and EPS impact liner, the A3 provides comprehensive protection against both high- and low-speed impacts. The integrated Mips® Brain Protection System helps reduce rotational forces transferred to the brain during angled impacts, while the reinforced shell construction enhances durability without adding unnecessary weight.
With 16 optimized intake and exhaust vents connected by deep internal channels, the A3 maximizes airflow to keep riders cool during demanding efforts. The Precision Fit retention system offers three-way adjustability, allowing riders to fine-tune the fit for all-day comfort and security. A moisture-wicking Ionic® comfort liner, featuring antimicrobial properties and a dedicated sweat-management system, helps keep perspiration under control on hot rides.
Trail-specific features include an adjustable visor with multiple positions for goggle compatibility, integrated eyewear storage ports, and premium finishing details throughout. The result is a helmet that delivers confidence-inspiring protection, outstanding comfort, and race-proven performance for every trail adventure.
