Giro Coalition Spherical Helmet
Product Details
The Giro Coalition Spherical helmet is a feather-light full-face mountain bike helmet, weighing just 800 grams (M/L). It combines Spherical Technology powered by MIPS with Progressive Layering using EPP and EPS foam for advanced protection. NTA-certified, it delivers best-in-class ventilation through massive front intake ports, rear exhaust vents, and deep internal channeling. The patent-pending Halo System integrates a Pebax chinbar with elastomeric bushings, absorbing and dissipating kinetic forces, exceeding standard chinbar deflection tests by nearly 2x. Comfort is enhanced with DryCore, sweat management, IONIC+ odor control, and removable cheek pads for a customizable fit. Ideal for trail riders, the Coalition Spherical sets a new benchmark for lightweight full-face protection.
