Giro Coalition Spherical Helmet

Spherical Technology acts like a ball-and-socket joint, allowing the outer liner to rotate around the inner liner during an impact. This design helps redirect impact forces away from the brain more effectively than traditional Mips slip-plane liners, which are typically fixed inside the helmet.

Because it weighs only 800g and features 23 vents with deep internal channeling, it is designed to be breathable enough for all-day trail riding. It balances the protection of a full-face helmet with the ventilation and weight profile of a lighter trail lid.

Yes, the helmet includes both 25mm and 30mm cheek pads, allowing you to swap them out to customize the fit around your jawline. This ensures the helmet stays secure without feeling overly tight or restrictive.

The Coalition uses a Halo chinbar system constructed with Pebax and elastomeric bushings. This setup is engineered to flex and absorb kinetic energy during an impact, rather than just acting as a rigid guard, which helps it exceed standard deflection certification testing.

The interior features a dedicated sweat management brow pad designed to keep moisture out of your eyes. Additionally, the liner materials are treated for odor control to keep the helmet fresh even after intense, sweaty rides.

Yes, the Coalition is highly certified, meeting NTA, ASTM-1952-DH, ASTM-2032-BMX, CE EN1078, and AS/NZS standards. It is built to handle the rigors of downhill mountain biking and BMX racing.
