This flip-up helmet is reminiscent of the 70's unique Simpson design, but with substantially improved noise reduction and aerodynamics. Simpson has given the Darksome a full suite of top-end features, based around an advanced Maxx -3C composite main shell, with an easy-to-use, high-tech polymer flip-up section making it a very light helmet, just 1,510g. An enlarged field of view provides a limit-less vertical and peripheral vision and the drop-down sun visor covers the whole field of view.
