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 push your limits. Our patented Live Fit technology uses 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. And the Ksyrium Pro Pad offers optimized support and cushioning, also featuring 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 to shield you from bugs. So even when the riding conditions heat up, you stay cool and comfortable start to finish.
