# Your Buddy on the Road: The Sphere Helmet
Your companion on the road, available in four sizes and created with our Advanced Rollsys® fit system, bringing ultimate comfort in a perfectly-fitting helmet. Eighteen cooling inlet and exhaust ventilation holes connected by carefully engineered air channels draw air from the front to the rear of your head, keeping you cool and ready to perform throughout your ride. On rainy days, the Sphere can be combined with the optional Aeroshell for added protection from the elements. Integrated eyewear docking, lightweight and thin straps, reflective stickering, and a ponytail-friendly rear head basket design add to the comfort and convenience.
