This is MAVIC's top women's endurance helmet for true long-distance warriors. It shares many of the same features and technologies as the Ksyrium men's helmet, which makes it lightweight and comfortable. The patented Live Fit SL flexible XRD(R) foam construction molds to your head shape for a precise, personalized fit with secure head hold and no hot spots. The Ergo Hold SL Retention system lets you fine-tune the fit with one hand, and the Sequence Pro Fit pad is lined with 37.5(R) technology to manage heat and wick away sweat five times faster than traditional liners. Adding to its head-cooling comfort, it features 22 Clima vents that circulate air around your head, so you can push the pace without overheating. This model includes the added protection of MIPS, a low-friction internal liner that can reduce the rotational motion that's transferred to the brain on angled impacts to the head. Go far, go fast and go with greater comfort and style with the Echappee Pro MIPS.
