Breathable, technical, and built to last. The Black Cycling Base Layer is made from lightweight ECONYL® regenerated nylon mesh that wicks moisture and regulates temperature on the move. A body-skimming sleeveless design sits smoothly under jerseys and winter layers without bulk — quick-drying and comfortable across every season. Made from regenerated nylon created from rescued ocean waste, in sizes 6 to 24, ethically made in Australia.
