Giro Coalition Spherical Helmet

Yes, it is fully certified for downhill and enduro riding. It meets ASTM-1952-DH and ASTM-2032-BMX standards, meaning it has passed rigorous testing for impact protection in high-speed, gravity-focused disciplines.

Mips Spherical uses a 'ball-and-socket' design where two layers of foam liner rotate independently around each other during an impact. This allows the helmet to redirect energy away from the brain more effectively than traditional slip-plane systems, which are typically just a thin plastic layer inside the helmet.

It is designed with 23 vents to maximize airflow, making it one of the more breathable full-face options available. While it will still be warmer than an open-face trail helmet, the ventilation is engineered specifically to keep you cool during intense efforts.

The fit is primarily managed through the included cheek pads. The helmet comes with two different sizes of cheek pads, allowing you to customize the fit around your face for a secure, stable feel without needing complex dial systems.

No, the chin bar is fixed and reinforced to provide maximum structural integrity for impact absorption. It is designed as a permanent, integral part of the helmet's safety architecture.

Yes, the Fidlock buckle is highly secure and specifically designed for gravity sports. It uses a magnetic guide to snap closed easily, but requires a deliberate sliding motion to release, ensuring it stays fastened even during rough, high-speed descents.
