COALTION SPHERICAL 

BIG TRAIL PROTECTION – ALL DAY COMFORT

Only Giro could engineer an impressively lightweight full-face helmet that still provides heavyweight protection. At a mere 800 grams in medium, this NTA-certified MTB helmet still packs the punch of Spherical Technology™, powered by Mips®, sandwiching our innovative integration of Mips in between independent EPP and EPS foam layers designed to optimize management of both high-speed and low-speed impacts. Coalition Spherical also manages to rival the ventilation and cooling power of some brand’s road helmets, pairing massive front intake ports with efficient rear exhaust vents via deep internal channeling.

Like many of our creations, one of Coalition’s most impressive innovations lies hidden inside: the 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.

With 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.
