How to use: Simply put on the jersey like any other top. The cam - lock zipper allows you to easily open and close it with one hand, which is very convenient when you're riding. The large 3 - pocket design at the back is great for storing small items like energy bars, keys, or your phone. Just make sure not to overfill them to avoid affecting your balance. Attention: When wearing, be aware that the tailored fit is designed to reduce wind drag but is not skin - tight. If you prefer a looser fit, you might want to size up. Maintenance: Machine wash the jersey in cold water with like colors. Avoid using bleach or fabric softeners as they may damage the performance fabrics. Tumble dry on low heat or lay it flat to dry. This will help maintain the fabric's moisture - wicking and ventilation properties, and keep the reflective accents in good condition.
