Giro Coalition Spherical MTB Helmet
The Giro Coalition Spherical MTB Helmet redefines lightweight full-face protection without compromising safety or comfort. Weighing only 800 grams in medium, this helmet incorporates advanced Spherical Technology™ powered by Mips®, which optimizes impact management through independent EPP and EPS foam layers. The innovative Halo System integrates a Pebax® chinbar and elastomeric bushings to absorb forces, exceeding standard chinbar deflection tests by nearly 2x.
Engineered for all-day wear, the Coalition Spherical features 23 vents with deep internal channeling to enhance airflow, rivaling the cooling power of road helmets. Ionic+™ treatments reduce odor, while interchangeable cheek pads allow you to fine-tune fit. Certified to meet NTA, CPSC, ASTM-1952-DH, and ASTM-2032-BMX standards, it’s ideal for downhill and BMX riders seeking top-tier performance.
