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. The Fathom™ helmet is a twin to our legendary Atmos™.

The compact design is a style leader and is matched with a removable adjustable visor and the two-way adjustable Roc Loc® 5 fit system. Offering the performance and versatility you need.
- Small = 51-55cm - Medium = 55-59cm - Large = 59-63cm
Features: Removable Visor, Roll Cage™ Internal Reinforcement
Construction: In-Mold Polycarbonate Shell with EPS Liner, Thermoformed SL Reinforcement
In-mold Construction: In-mold construction fuses a tough polycarbonate outer shell with the helmet’s impact-absorbing foam liner. The fusion process allows us to sculpt better ventilation systems, so In-mold helmets can be lighter and cooler than traditional helmets.
X-Static Padding: In addition to being very comfortable, our X-Static pads provide anti-microbial properties to help keep your helmet fresher, longer. The pads are also machine washable.
Roll Cage™: Roll Cage reinforcement is a tough web of DuPont® Nylon® molded inside a helmet’s EPS foam liner. It provides an extra measure of strength and integrity that you’ll never notice… unless you need it.
Roc Loc® 5: After more than two-years of development, Giro introduces Roc Loc 5. This groundbreaking fit system provides an entirely unique user experience with an unmatched level of comfort, stability, adjustability and weight savings. With Roc Loc 5, you can easily dial-in both fit tension and adjust vertical position with a single hand. Just twist the dial for a tighter feel on rough terrain, then back it off a notch and relax across the flats or a warm climb. Even with these remarkable features, Roc Loc 5 is still nearly 40-percent lighter than its popular predecessor, Roc Loc 4.
