The layer closest to your skin should get the most consideration. Temperature regulation and moisture management are critical to your performance and comfort during a ride, which is why base layers can be an amazing upgrade to any cycling kit. No other base layer beats the sleeveless Chrono SL Base Layer, built from our proprietary Wikpro™ fabric with a seamless body design, when it comes to fit and performance. Wikpro is a performance-engineered blend of polypropylene and nylon knit that offers amazing moisture transfer and breathability with an incredibly soft feel against the skin, plus exceptional stretch and rebound for a second-skin-like fit. Once you try it, you won't want to ride without it.​​
