Rudy Project helmets are appreciated because of our legendary fit, the result of studies into ergonomics, design and material innovation and advanced manufacturing techniques. The retention system is constantly updated to improve comfort and performance. The new RSR 9 system enhances your fitting. The structure is more wrap-around while precise micro-metric regulation and height adjustment provide a perfect personal fit. The airframe frontal padding is crafted with innovative materials such as Dry Foam and X-Static antibacterial fabric: the former is a special white foam which does not absorb the sweat while the latter favours transpiration. The padding minimizes the sweating process inside the helmet: the foam does not absorb the sweat while the fabric easily transpires and dries, avoiding the release of unpleasant smells and ensuring the best level of performance.
