The R4K Race Collar features a revolutionary Koroyd core with superior impact absorption and a reinforced nylon upper shell. The chassis has been completely redesigned to be lighter and more aerodynamic. In an impact, the head is pushed down on the race collar which effectively fills the gap between your helmet and shoulder, the Koroyd material was designed to absorb impact energy better than standard race collar materials.
