Winding mountain roads and coastal byways are even more enjoyable when your helmet is so comfortable that you don't even notice it as you ride. Mavic's Ksyrium Pro Helmet is designed to let you focus on the ride with a blend of long-mile comfort, road-worthy protection, and a unique aesthetic that the company's helmets have become known for.Mavic starts by shaping the Ksyrium Pro to provide coverage on the vulnerable areas of the back of the head while ensuring the helmet remains lightweight and breathable, a goal that was facilitated by ample ventilation throughout. Within the helmet, Mavic helps create a more comfortable fit next to your skin by using its Live Fit technology, which involves a band of plush, adaptable XRD memory foam spanning the front of the helmet. This foam customizes the fit to your head shape to ensure a secure fit that absorbs road vibrations and disperses impact in the event of a crash.
