Giro Fathom Helmet.

Leading performance and style. If you ride everything and ride fast, you need the same cool comfort and performance whether you’re on the open road, or your favourite singletrack.

The 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.
