The 100% Altis Gravel Helmet is a lightweight helmet for head safety while gravel bike riding. Gravel riding lives somewhere between road and trail, and this helmet protects your noggin while in the saddle. Featuring the 11-point Smartshock Rotational Protective System, you're also protected against rotational forces in the event of a crash. Keep a cool head in all situations thanks to 14 vents and a moisture-wicking and anti-microbial liner that is washable in case things get really funky.
