The pinnacle helmet in Smith’s performance road collection is the all new Trace. The Trace features Koroyd, which fully surrounds the helmet providing exceptional protection and works with the internal air channels and open intake and exhaust ports to produce maximum ventilation. Storage and ventilation of eyewear is crucial on those long rides, the Trace’s AirEvac system relieves hot air that builds up on your eyewear to prevent fogging. Eyewear storage is made easy by channels on the side of the helmet that hold your eyewear in place for those grueling climbs.
