Troy Lee Designs A1 AS Classic Helmet with MIPS

Troy Lee Designs introduced the A1 helmet in 2013. Today, It's still one of the most comfortable MTB helmets on the market, made even safer with the addition of MIPS rotational brain protection. 

This lightweight, fully encapsulated all-mountain helmet utilizes maximum coverage and dimension to keep you safe and protected in all riding conditions. When the action heats up, the 8 intake and 8 exhaust vents allow air to flow through the helmet and cool the head. The moisture wicking one-piece anti-microbial liner sheds water quicker than regular padding and is washable. With the A1 helmet, we at Troy Lee Designs returned to the aggressive all-mountain half shell category.
