Designed with four strategically placed polyester blends for maximum stretch, moisture wicking performance, and breathability, the Craft Men's Tech Aero Short Sleeve Jersey offers the very best in cycling comfort and mobility. Micro polyester fabric located throughout the body features multi channel fibers for enhanced moisture transport and evaporation, ultimately keeping you cool and comfortable on the warmest days of the year. Mesh Superlight fabric along the underarms combats perspiration by channeling cooler outside air over your arms when you're cycling. Moving Wing Technology promotes freedom of movement when you're dropping into an aero position and powering up long, strenuous uphills. Soft silicone grippers at the arms and back hem provide a secure fit without uncomfortable pinching. Furthermore, you'll appreciate the jersey's four rear pockets, one of which is zippered with a headphone port, for seamlessly routing your cords and storing riding accessories.
