The AGU Essential Women's Long Sleeve Thermal Cycling Jersey in Yellow combines the performance of a lightweight cycling jersey with the warmth insulation of a thermal jacket, making it suitable for cooler weather conditions. Made from highly breathable Summerit polyester fabric, it offers effective thermal insulation while ensuring soft comfort against the skin. This technical fabric retains heat in dropping temperatures without compromising moisture regulation. Reflective elements enhance visibility in low light conditions for increased safety. The high-pile collar provides neck protection against cool winds, while the Camlock zipper system allows for partial opening without fully unzipping for convenient ventilation control. Three rear pockets offer practical storage solutions, including one with headphone cable access for electronic devices. A silicone gripper at the hem ensures secure jersey positioning during active movement. Available in multiple color options, this thermal cycling jersey effectively serves as an outer layer in cool conditions or as a mid-layer in colder temperatures. The women's specific cut and medium size provide a comfortable fit for cycling activities in the fall and winter seasons. The material composition is 100 percent polyester with dimensions optimized for athletic performance and thermal efficiency.
