The lightweight Giro Coalition Spherical combines Spherical Technology powered by Mips and Progressive Layering featuring both EPP and EPS foam, with best-in-class ventilation and the added protection of our innovative Halo System chinbar.

Only Giro could design an impressively lightweight full-face helmet that still provides heavyweight protection. Just 800 grams in M/L, this NTA-certified MTB helmet still packs the punch of Spherical Technology™ powered by Mips® while Progressive Layering with EPP and EPS foam optimizes management of both high-speed and low-speed impacts. Coalition Spherical delivers best-in-class cooling power by pairing massive front intake ports with efficient rear exhaust vents via deep internal channeling. Coalition's most impressive innovation lies hidden inside: the patent-pending Halo System combines a chinbar with Pebax® (a material that is engineered to provide the perfect range of flex and rigidity) and elastomeric bushings that are integrated into the EPS to absorb and dissipate kinetic forces. The result is a helmet that exceeds standard chinbar deflection certification testing by almost 2x. Comfort is maximized with the DryCore™ sweat management brow pad, IONIC+™ treatments to control odor, and two sets of removable cheek pads to help fine-tune fit. The Coalition Spherical sets a new benchmark for lightweight full-face protection.

SPECS:

  • Construction: In-Mold polycarbonate shell with EPS liner
  • Ventilation: 23 vents with deep internal channeling
  • Fit System: Comfort Liner/Neck Roll/25mm & 30mm cheek pads
