Troy Lee Designs A2 MIPS Dropout

Cooler, faster, in a protective package—the A2

The A2 helmet redefines mountain bike safety, style, comfort, and ventilation. The first helmet in its class to combine EPP (for slow speed impacts) and EPS (for high speed impacts) in one sleek package, that will set a new benchmark for mountain bike helmets.

A2 Functional Features:

- Huge air intakes - 25% larger than A1 - connected to massive exhaust ports through deep internal channels provide powerful cooling efficiency
- MIPS brain protection system reduces rotational forces to the brain in some crash scenarios
- Dual-density EPS, co-molded with EPP, for state-of-the-art impact energy management at low and high crash speeds as well as everything in between
- 16% more EPS+EPP in the frontal lobe and raised EPS splines provide more protection in the common impact zones
- Aerospace filament-reinforced polycarbonate shell
- Break-away anodized aluminum visor screws

Fit:

- Rear stabilizer fit system with flexible, slimline arms has 3-position front and rear locations for a custom fit
- Expanded field of view works with both goggles and glasses – multiple storage locations for glasses
- Low-profile fixed strap dividers for a no-fuss fit every time
