The lightweight engineered knit Men's Chrono Base Layer does just that. It features nylon thread to ensure a soft feel, while polyester content pulls moisture away from your skin. It has enough stretch to allow freedom of movement and fit your body comfortably. It's also extremely light and tucks easily under a bib short without any bunching. A good base layer should enhance the riding experience, not distract from it. With soft-feeling and moisture-wicking properties, the Chrono™ Sleeveless Base Layer is the ultimate layer.
