The all-new Troy Lee A2 helmet redefines mountain bike safety, style, comfort and ventilation. The A2 combines EPP (for slow speed impacts) and EPS (for high speed impacts) in one sleek package. MIPS (Multi-directional Impact Protection System) technology lets the helmet slide relative to the head, adding more protection against rotational violence to the brain caused by angled impacts. The A2 features 25% larger air intakes than the A1 and large exhaust ports to provide powerful cooling efficiency.
