The R4K is an all-new racing collar for 2016. It features a revolutionary Koroyd core with superior shock absorption and a reinforced nylon upper shell. The chassis has been completely redesigned to be lighter and more aerodynamic. In an impact, your head is pushed down onto the racing collar. The R4K effectively fills the gap between your helmet and shoulder with Koroyd, which absorbs impact energy better than standard racing collar materials.
Koroyd core designed for superior shock absorption.
Reinforced nylon upper shell.
Lightweight, aerodynamic chassis design.
Rapid easy front entry closure system.
Integrated X-Strap cleats.
Polyurethane foam base.
Koroyd Engineered Base:
Superior Energy Absorption: The Koroyd structure has extremely efficient and consistent energy absorption properties. The cores decelerate the energy of an impact to reduce final trauma levels.
Light on Weight - Strong on Performance: Koroyd is an extremely lightweight core, made of 95% air.
Performs When Heat Is On: Koroyd's mechanical properties remain stable in extremely hot and cold environments. Traditional energy absorbers suffer from reduced energy absorption capabilities as they become hot and soft or cold and brittle.
