Cooler, Faster in a Protective Package

The trailblazing A2 is Troy Lee Design's MTB trail helmet that checks all the boxes. Its stylish shell not only incorporates huge intake and exhaust ventilation ports, but it also comes with the very best impact protection.

From breakaway visor screws and the innovative MIPS® system and an industry-first dual-density EPP + EPS liner that protects against both high and low-speed impacts; this is a helmet that doesn't take your safety lightly. Add in an adjustable strap and X-Static® Pure Silver comfort liner and the comfort is every bit on par with the protection.


  • Cutting-edge safety technology with the MIPS (Multi-directional Impact Protection System)
  • Patent-pending, dual-density EPP = EPS impact liner provides protection against high and low-speed impacts
  • An additional 16% more frontal EPP + EPS increases protection in common impact zones
  • 25% more airflow over the A1 for maximum cooling power using huge intake and exhaust ports
  • X-Static® Pure Silver comfort liner with extended coverage, odor protection, and quick-dry moisture wicking
  • Innovative break-away visor screws help reduce the likelihood of snagging during a crash
  • Low-profile, semi-adjustable strap dividers deliver the perfect fit regardless of head shape
