How to use: Just put on the jersey like you would any other shirt. You can use the pockets to carry snacks, your phone, or other small items. The zippered security pocket is great for keeping your wallet, keys, or other important things safe. When you're riding, adjust the fit to your comfort. Notice: Avoid sharp objects that could tear the fabric. Don't overfill the pockets to maintain a good balance. Maintenance: Wash the jersey in cold water with a mild detergent. Hang it to dry instead of using a dryer to keep the fabric in good condition.
