The Fox Proframe RS Helmet was designed from the ground up to be the lightest, most effective, and most comfortable full-face Fox has ever produced. Although light on weight, the Proframe RS is heavy on protection, featuring a Varizorb EPS foam inner shell to protect against both high and low-speed impacts along with MIPS Integra technology to further protect the brain from rotational forces. Advanced in-moulding allows the shock-absorbing inner shell to be securely fused to the robust polycarbonate shell making a helmet that is significantly lighter and better ventilated. Speaking of ventilation, the Proframe RS has twenty-four big bore vents which help channel air through the helmet for maximum cooling.
