Giro Fathom Helmet

If you're a multi-bike rider, you're probably familiar with how light, breathable, and comfortable road helmets can be, and have probably wished your mountain helmets could compete. Maybe you've even taken to wearing road helmets off-road, and deflecting the inevitable comments about spandex, shaved legs, and Lance. Well, the Giro Fathom can't do anything about your riding partners' senses of humor, but since it's an Atmos with a visor, you'll be just a bit more incognito. It gets the same, thermoformed Roll Cage SL, the Roc Loc 5 adjustment Giro helmets are famous for, and 26 vents to keep you cool, even on long, exposed, hot climbs.
