EVS took their proven race collar technology and stepped it up to the next level. The new R4 Pro improves upon existing lightweight feel and incredible fit by incorporating the use of carbon fiber, high-impact injection grade bio-foam and an all new innovative air bladder shock absorption system. In addition, EVS improved the harnessing system by providing an all new bi-lateral torso strapping system.

Rapid Lock Front Closure - Makes getting in and out of the collar fast, easy and safe.
Carbon Fiber Top Cap - Absorbs and disperses energy to the bio-foam and air bladder system.
Integrated Air Bladder Shock Absorbing - Eases the tension on shoulders / spine when faced with direct impact from helmet; deflects and absorbs the impact energy through a deformation that uses energy, while also dispersing energy, thereby evening out the forces across the body naturally.
Adjustable Rear Strut - Offers adjustments of 10 - 12 between pin locations for a more customized fit.
Rear Axial Load Absorber "Tail" - Transfers impact energy across width of shoulders instead of blunt force to spine.
Bio-Foam Liner - Serves as an extra layer of absorption while offering added comfort; removable / washable.
Bi-lateral torso strapping system (X-Strap Harness) - Ensures a safe, secure fit throughout the entire duration of your ride.
