Product Info

The Smith Mainline MIPS Bike Helmet takes the brand headfirst into a highly contested scene, and their first full-face is a winner. As lightweight and as comfortable as their half shells, the Mainline will shock you with its airy feel. If you're challenging yourself with bigger terrain and higher speeds, the confidence you'll get from this full-face is a welcome addition. You charge, but so do dentists: rock a full-face and only see them at your six month checkups!
