At the forefront of Smith's new Performance Road Collection is the new Trace. It features Koroyd®, which envelops the entire helmet and offers remarkable protection. Along with the internal ventilation channels and the open air inlets and outlets, it provides maximum ventilation. The attachment and ventilation of the goggles are extremely important factors on long rides; this is where the AirEvac system comes into play. It directs the hot air that builds up above the goggles away, preventing any fogging. The channels on the side of the helmet are responsible for securely holding the goggles in place, even during the steepest climbs.
