All trails deserve elite-level, open-face performance The all-new Speedframe RS Matte Black Helmet takes the fit, breathability, and performance of the much-loved Speedframe and elevates it to the next level of safety and performance. Featuring the all-new and exclusive Mips® Integra Split protection system, which combines an impact-savvy, dual-density foam layer and a Low Friction Layer between the two, to reduce rotational forces in a crash that would otherwise be transmitted to the brain. In addition to this added level of safety and performance, you'll find the BOA® Fit System, 3-position visor, FIDLOCK closure system, and - new for Speedframe - sunglass holder ports.
