The Aircraft 2 Helmet is a top-tier helmet that delivers lightweight function and superior protection when our routine run leaves us unexpectedly flying into the bushes. And, 100%'s Smartshock technology delivers both impact and rotational protection so we're prepared for anything and everything. 100% crafts the shell using carbon fiber that balances a low weight with high strength, and maximum airflow comes thanks to a total of 20 ventilation ports that keep breathability up. Protection does not come at a hot and unhygienic price, though. A washable anti-odor liner increases the comfort factor and leaves us feeling fresh post-wash.
