The all-in helmet.

The Sphere is your buddy on the road. It comes in 4 sizes with the Advanced Rollsys® fit system for a comfortable, precise fit. 18 vents and internal air channels pull air from front to back to keep you cool on long rides. On rainy days, pop on the Aeroshell to keep out the weather. The details are covered too: eyewear docking, thinner straps, reflective stickers and a ponytail-friendly rear.

Pop on the Aeroshell, a polycarbonate cover sold separately, to keep out rain, snow and mud. It also closes the front and side vents for an aero advantage.

Eyewear docking

An extra polycarbonate layer is molded into the foam. Like a rally car's roll cage, it holds the foam together after a crash for added protection if you hit again.
