The Bauer IMS 11.0 Helmet is among the most advanced available. It features the patented Seven Technology Attenuation liner, which disperses energy by laterally compressing, then resets within seconds. The ProFit2 Extreme gives a true 360 degree fit that is tool-free and can be adjusted with one hand. PORON XRD foam is strategically added for ultimate protection. The helmet is pro-styled with a low-profile look.
