Troy Lee’s A2 has become a popular seller here at the shop thanks to a comfy fit and keeping your head cool on the hot days. This tried and true lid now comes in some new color options! 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.
