Long winding descents and race-day lead-outs, the Smith Trace is all about versatility. Road, gravel or bikepacking, this bike helmet pairs complete KOROYD® with Mips® for protection you can trust if the route gets hairy. And when the day heats up, you'll stay cool thanks to internal air channels with intake and exhaust ports that keep the air flowing. Side channels let you securely stash your sunglasses when you don't need them, and when you do, our AirEvac ventilation system prevents them from fogging up.
