When you spend long hours in the saddle, your gear choices are critical. Your comfort affects your speed and endurance. This helmet is made with advanced fit technologies, protection and ventilation to help you ride farther and faster with long-lasting comfort. The integrated MIPS brain protection system makes protection a top priority. It’s designed with a low-friction layer between the helmet shell and the liner. This allows the helmet to slide relative to the head in the case of a crash or impact, reducing the rotational energy and forces that are transferred to the brain. The Ksyrium Pro MIPS also features our patented Live Fit technology on the MIPS layer, with XRD foam construction that molds to your head shape with a precise, personalized fit. The Ergo Hold SL retention system allows you to fine-tune that fit, quickly and easily with just one hand. The Ksyrium Pro Pad offers optimized support and cushioning. It’s made with 37.5® technology, which uses active particles to absorb heat from your head and wick sweat away five times faster than traditional fabric. There’s even a mosquito mesh on the inside of the frontal vents to shield you from bugs. So even when the riding conditions heat up, you stay cool and comfortable from start to finish.
