With a racing fit and breathable design, the Trek Segafredo Replica Jersey from Santini lets us feel like we're a pro, even if we're just out for our afternoon training session. Microfiber polyester materials are ideal for the hottest days and work in conjunction with full-length mesh side panels, and elongated, raw-cut sleeves enhance aerodynamic performance and comfort for our most intense rides. As can be expected with a jersey like the Replica, a full-length zipper gives us total control over ventilation, and three open rear pockets leave room for all of our essential items like snacks, keys, gels, or an extra layer.
