Giro Fathom Mountain Bicycle Helmet. 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 Bicycle Helmet is a twin to Giro's legendary Atmos, a break through Bicycle 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 Bicycle Helmet.
