The Mavic Ksyrium Pro MIPS Helmet provides unparalleled comfort across long distances with its ergonomically contoured shape and head-conforming XRD foam. This means it'll sit precisely on your head without any pressure points or uncomfortable hot spots causing you to constantly re-adjust the helmet through long-distance endurance efforts. Mavic's Ergo Hold SL Retention System wraps around your head with the twist of a rear-mounted dial, allowing the helmet to fit precisely without excess movement at high speeds. You're probably aware of MIPS by now, but we'll explain this leading impact-dissipating technology in a brief manner. Basically, this technology places a low-friction liner inside, which allows the helmet to rotate independently around your head, should you take a spill at an oblique angle with the asphalt, which is most likely to occur. This allows the helmet to dissipate rotational impact forces from being transmitted through the helmet, instead of just offering protection from head-on collisions like a traditional cycling helmet. Besides its ergonomic shape and upgraded MIPS technology, the Ksyrium Pro MIPS employs 22 Clima Vents to rapidly evacuate built-up heat from cooking your head in warmer weather. Another impressive feature are the 37. 5-embedded pads for moisture management and temperature regulation. This technology uses heat-activated charcoal sourced from volcanic sand and coconut shells to quickly wick moisture where it can readily evaporate, promoting an utterly cool, dry feel when you're sweating it out on the road.
