A-Series Helmets Compared
Troy Lee Designs A1, A2 and A3—the benchmarks for protection, coverage and comfort in mountain bike trail helmets. The iconic OG A1 set the bar for modern open-face helmets, and continues to be the number one go-to for groms and adult riders looking for low-cost head protection. A2 raised the bar again, with more comfort, more ventilation and more aggressive styling. And the all-new A3 is simply a trail-helmet masterpiece—it’s built with ALL the features and is so comfortable that you’ll never want to take it off.
