Giro Coalition Spherical Cycling Helmet Charcoal Rush -L 59-

Only Giro could create an impressively lightweight full-face helmet that still packs a heavy-duty punch.
At just 800 grams (size M), this NTA-certified MTB helmet still packs the power of Spherical Technology™ powered by Mips®, where our innovative integration of Mips is sandwiched between independent EPP and EPS foam layers designed to manage both high-speed and low-speed impacts.
Coalition Spherical also manages to match the ventilation and cooling power of some brands’ road helmets, combining massive intake ports up front with efficient exhaust vents in the back via deep internal channels.
As with many of our creations, one of Coalition’s most impressive innovations lies hidden inside: the Halo System, which combines a chinbar with Pebax® (a material designed to provide the perfect range of flex and stiffness) and elastomer bushings integrated into the EPS to absorb and dissipate kinetic forces.
The result is a helmet that nearly 2x exceeds standard chinbar deflection certification tests.
With Ionic+™ treatments to control odor and two sets of removable cheek pads to fine-tune fit, the Coalition Spherical sets a new benchmark for lightweight full-face protection.
