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.
The combination of Koroyd's precise and unique thermal welding process leads to a structure with both extremely efficient and consistent energy absorption properties. Upon impact, the cores crush in a completely controlled manner, decelerating the energy from the impact and reducing the final trauma levels.
Koroyd is an energy absorber which is fully breathable and doesn't compromise impact performance. Koroyd's open cell construction allows cool air in, while expelling hot air from the rider's head. The completely open cell construction integrates with internal channels to create the full Aerocore construction to provide ventilated protection.
Thousands of co-polymer extruded tubes, thermally welded to create an unparalleled consistent and fully engineered core. Each Koroyd section is engineered to precise durometer, size, and thickness specifications to provide the greatest impact resistance and aesthetically consistent presentation.
MIPS - Multiple Impact Protection System
MIPS is used to reduce the rotational forces to the brain in the case of an oblique impact. Smith helmets are created to absorb direct impacts very efficiently and when combined with MIPS, Smith helmets absorb oblique forces better by allowing a small rotation of the outer shell relative to the liner.
