Advanced Protection with Spherical Technology
Spherical Technology’s ball-and-socket design, powered by Mips, allows the outer liner to rotate around the inner liner during a crash. This helps redirect impact forces away from the brain while eliminating direct contact with hard plastic slip-planes.
Halo System Chinbar
The patent-pending Halo System uses a Pebax-engineered chinbar and elastomeric bushings integrated into the EPS to absorb and dissipate kinetic forces. This design exceeds standard chinbar deflection certification by nearly 2x, offering exceptional protection without adding weight.
Lightweight Performance with Progressive Layering
A combination of EPP and EPS foam manages both high-speed and low-speed impacts, delivering comprehensive protection in a lightweight package. At just 800 g in M/L, the Coalition Spherical is impressively light for a full-face helmet with this level of safety.
Best-in-Class Ventilation
Massive front intake ports, deep internal channeling and efficient rear exhaust vents create a powerful airflow system that keeps you cool on climbs and during intense descents.
Comfort and Fit for Long Days
The DryCore sweat management system redirects moisture away from your brow, while IONIC+ padding controls odour and keeps the helmet feeling fresh. Two sets of removable cheek pads allow you to fine-tune the fit, and the Fidlock magnetic buckle offers quick, secure closure.
