If you ride everything and ride fast, you need the same cool comfort and performance whether you’re on the open road or your favorite singletrack. Giro's Fathom is a twin to the legendary Atmos, a breakthrough helmet design that offers amazing ventilation thanks to a clever internal reinforcement structure. The compact design is a style leader, and matched with a removable adjustable visor and the two-way adjustable Roc Loc 5 fit system, offers the performance and versatility you need.
