Race collars are often overlooked, but are an essential component to any rider’s gear set and offer increased neck protection and confidence.
The Outer Shell is the R4K’s first line of defense. It protects the rider by deflecting downward impact force.
Koroyd’s unique honeycomb structure is stronger, and lighter than the materials used on most other race collars.
The R4k’s Koroyd core (A) is encased in High Density EVA Foam (B), and Exterior Impact Shell (C) provide optimal impact absorption.
The R4Kfeatures 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.
