Giro Fathom MTB Helmet
Built on the same platform as Giro's legendary Atmos, the Giro Fathom MTB Helmet provides amazing ventilation, thanks to an innovative internal reinforcement structure and its sleek, compact design combines groundbreaking style with off-road performance. In-Mold polycarbonate shell with EPS liner provides excellent impact protection and allows for bigger vents, all while remaining incredibly lightweight. New Thermoformed SL Roll Cage, a polycarbonate skeleton fused throughout the helmet's impact absorbing EPS foam liner, gives structural support, impact dispersion and penetration resistance. 23 Wind Tunnel vents cool your entire head as it forces heat and stale air to the outside. P.O.V. visor allows 15° of vertical adjustment on-the-fly and Roc Loc 5 retention system puts unrivaled fit and adjustability at your fingertips.
