The R4 Pro improves upon existing lightweight feel and incredible fit by incorporating the use of carbon fiber, high-impact, injection-grade BIOFOAM and innovative air bladder shock absorption system. Improved harnessing system by providing a bilateral torso strapping system. Makes getting in and out of the collar fast, easy, and safe. Absorbs and disperses energy to the BIOFOAM and integrated air bladder system. 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.
