How to use: Just put on the jersey like you would any other shirt before your cycling trip. It's designed to fit well and offer great comfort during long rides. Note: Always refer to the sizing chart to ensure you get the right fit. If you're between sizes, it's often better to go for the larger one for more comfort. Maintenance: Wash the jersey in cold water to preserve the fabric quality and the UPF rating. Avoid using harsh detergents as they can damage the QuickDry and waffle - textured fabrics. Hang it to dry instead of using a dryer to prevent shrinking and damage to the stitching. With proper care, this jersey will serve you well for many cycling adventures.
