Why wear a race collar?

Race collars are often overlooked, but are an essential component to any rider’s gear set and offer increased neck protection and confidence.  

Outer Shell

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.
