Why We Like The Giro Coalition Spherical Helmet
Lightweight, advanced tech, and a protective design are everything we need for aggressive riding. The Giro Coalition Spherical Helmet is our new go-to helmet for full-face protection. The Giro Coalition Spherical Helmet has an in-molded polycarbonate shell for a lightweight and durable design with 23 vents, so we stay cool even on the hottest days. This helmet features a dual-density EPP and EPS liner to absorb impacts, and a Mips Spherical technology acts as a slip plane between the helmet and our head so we can minimize energy from angled impacts. The Halo chin bar system has been reinforced with Pebex and elastomer bushing to give the chin bar flex and absorb kinetic energy.

Nice snug fit. Great for oval heads.
- Familiarity:
- I've used it several times
I have logged about 100 miles with the Giro Coalition. Out of the box I had to use the smaller of the neck pads and run the smaller cheek pads. I have a very oval head and this is one of the few helmets that fit. If you have a wider jaw I would suggest sizing up. The spherical mips had no squeaking. The interior liner is comfortable.
