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. But high performance means nothing without exceptional fit and comfort. That's why no other base layer beats the Chrono SS Base Layer, built from our proprietary Wikpro fabric with a seamless body design. Wikpro is a performance-engineered blend of polyester 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.
