A1 MIPS: Fit, Coverage and Style

Here at TLD, styling, graphics, fit, function and coverage are key in everything we create. After years of research and development, the Troy Lee Designs Team introduced the A1 helmet in 2013. We made one of the most comfortable MTB helmets on the market with the addition of MIPS.

This lightweight, fully encapsulated all-mountain helmet utilizes maximum coverage and dimension to keep you covered in all riding conditions. Whether you're charging single track, riding dirt jumps, or grinding out miles on the XC bike, the A1 helmet offers the premium fit, coverage, and style you want.
