Giro Coalition Spherical
Only Giro could design a full-face helmet this impressively light while still delivering uncompromising protection. Weighing just 800 grams in size medium, this NTA-certified MTB helmet features Spherical™ technology, developed by Mips®, which innovatively integrates independent EPP and EPS foam layers designed to optimize impact management at both high and low speeds. The Coalition Spherical also rivals the ventilation power of some brands’ road helmets, combining massive intake ports at the front with efficient exhaust vents at the rear, linked by deep internal channels. As with many of our creations, one of the most impressive innovations of the Coalition is hidden inside: the Halo system combines a Pebax® chinbar (a material engineered to offer the perfect balance of flexibility and rigidity) with elastomer pads integrated into the EPS to absorb and dissipate kinetic forces. The result is a helmet that exceeds standard chinbar deflection tests by nearly 2x. With Ionic+™ treatment for odor control and two sets of removable cheek pads to help fine-tune the fit, the Coalition Spherical sets a new benchmark for lightweight full-face protection.
