Product Details

Big Trail Protection - All Day Comfort.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.

MAXIMIZED REAR EXHAUST VENTS

Our complex Wind Tunnel venting system allows hot air an easy escape route from the rear of the helmet.

Breakaway Visor Bolts

Tool-free breakaway visor bolts are engineered with an integrated Allen key receiver for easy removal and replacement in case of crash.

FIDLOCK® Magnetic Buckle Closure

The pinch-free one-handed Fidlock® magnetic snap helmet buckle combines the advantages of two fastening concepts in a completely new way: Strong magnets make it easy to open and close, while a secure snap functionality ensures a continuous locking force.

DryCore™

The DryCore™ sweat management system utilizes an internal silicone bead to redirect moisture away from the rider's brow and eliminate the irritation of sweat dripping into the eyes.

Deep Internal Channeling

Combined with the massive vents, internal channeling forces air to flow over the scalp, providing remarkable cooling power.

HALO SYSTEM CHINBAR

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.

Spherical Technology

Spherical Technology's ball-and-socket design, powered by Mips®, helps redirect impact forces away from the brain by allowing the outer liner to rotate around the inner liner during a crash. It also eliminates contact with hard plastic or slip-planes against the skin.

IONIC+ ® Padding

Pure silver is the secret ingredient that gives IONIC+ ® the power to provide natural, permanent odor protection to keep your helmet feeling fresh.

Directional Snap System

In case of emergency, cheek pads are easily removable without disturbing the riders head and neck position.

Optimized Front Intake Vents

Giro engineers designed precise placement and shape of intake vents to optimize cool air flowing over riders' heads.
