How to use: Just put on this jersey before your cycling trip. You can adjust the long front zip according to your comfort level. Use the three open back pockets to store things like snacks, maps, or small tools, and keep your valuable items in the zipped security pocket. Note: Don't over - stuff the pockets to avoid affecting your riding comfort. When washing, turn the jersey inside out and use a mild detergent. Wash it in cold water and avoid using a dryer to keep the fabric in good condition. Hang it to dry instead.
