If you ride everything and ride fast, you need the same cooling comfort and performance whether you're speeding along your favorite singletrack or the open road. The Giro Fathom Mountain Helmet is a twin to Giro's legendary Atmos, a break-through 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 all the performance and versatility you demand in a marquee helmet.

- 23 Wind Tunnel vents and internal channels deliver superb ventilation
- Roc Loc 5 retention system for easy, single-handed adjustment and a custom fit
- Anti-microbial X-Static padding offers unprecedented comfort and manages moisture
