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.

Technologies:

• Wind Tunnel™ Ventilation: Giro helmets are developed utilizing the proprietary Wind Tunnel™ ventilation system. This elaborate design combines active vents in the helmet’s shell with exhaust channels inside the helmet that thrust fresh, cool air over and around the rider’s head while forcing heat and stale air out. It’s the most effective cooling system available, and a difference you can feel every time you ride.
• Super Fit™Engineering: Our proprietary Super Fit™ sizing system is based on “human scale factors” data and over 25 years of handcrafting helmets. By creating helmet moulds in up to 4 adult sizes to match the human body’s form, our Super Fit™ sizes comfortably and securely fit riders, and feel like they are custom made just for you.
• Roll Cage™ Reinforcement: Roll Cage™ is a light-yet-tough web of reinforcement invisibly molded inside a helmet’s EPS foam liner. It helps the helmet to hold together under impact, and provides an extra measure of strength and integrity that you’ll never notice...unless you need it.
• Roc Loc® 5 Fit System: The industry benchmark in comfort, stability, adjustability and weight savings. In addition to enhancing the fit and comfort of helmets, Roc Loc® 5 allows you to easily custom tune the fit tension and the fore-aft tilt of the helmet in seconds using a single hand. And it’s lighter than comparable systems too, making it the ultimate in skull-hugging luxury.
• In - Mould Construction: In-Mould Construction fuses a tough polycarbonate outer shell with the helmet's impact-absorbing foam liner. The fusion process allows for better ventilation systems, making in-mould helmets lighter and cooler than traditional helmets.
