TLD A1 Helmet

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.

A1 is perfect for the MTB rider just starting out with mountain biking or eMTB or the expert rider on a budget

I had another A1 (non-MIPs) that I got ~4 years ago. It's worked very well for me. I have a large oblong head and wear a XL-XXL which fits me perfectly. I recently broke the visor on the old one and it was getting rather tatty so with the great price on this new MIPs version, I got it. It fits the same. Ventilation is good. It is a bit bulky and heavy but not consequentially so.
