Advanced Protection with Spherical Technology
Spherical Technology uses a ball and socket design that allows the outer liner to rotate around the inner liner during a crash. Powered by Mips, this system helps redirect rotational 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 downhill rated chinbar exceeds standard deflection testing by almost 2x, offering exceptional protection without adding unnecessary weight.
Lightweight Performance with Progressive Layering
Dual density EPP and EPS foam work together to manage both high speed and low speed impacts. At just 800 g in M/L, the Coalition Spherical is one of the lightest full face MTB helmets to offer this level of protection.
Best in Class Ventilation
Massive front intake vents, deep internal channeling and maximised rear exhaust ports create a powerful airflow system that keeps riders cool on climbs and during long descents. This makes the Coalition Spherical one of the best ventilated full face mountain bike helmets available.
Comfort and Fit for Long Days
The DryCore sweat management system redirects moisture away from the brow, while IONIC+ padding controls odour and keeps the helmet feeling fresh. Two sets of removable cheek pads allow fine tuning of fit, and the Fidlock magnetic buckle provides quick, secure closure.
