Spherical Coalition

Only Giro could engineer a full-face helmet that's impressively light while still delivering heavyweight protection. At just 800 grams in M/L, this NTA-certified MTB helmet still features Spherical Technology™ powered by Mips®, while progressive layering with EPP and EPS foams optimizes high- and low-speed impact management. Coalition Spherical delivers best-in-class cooling power by pairing massive intake ports up front with efficient exhaust vents in the rear via deep internal channels. Coalition's most impressive innovation is hidden inside: the patent-pending Halo System combines a chin bar with Pebax® (a material designed to provide the perfect range of flexibility and stiffness) and elastomeric rings integrated into the EPS to absorb and dissipate kinetic forces. The result is a helmet that exceeds chin bar deflection certification tests by nearly 2x. Comfort is maximized with the DryCore™ forehead pad that manages sweat, IONIC+™ treatments that control odor, and two sets of removable cheek pads that allow for a more precise fit. The Coalition Spherical sets a new standard for lightweight full-face protection.
