How to use: Just put on the jersey before your summer bike ride. The cam - lock zipper allows for easy single - hand operation when you're on the move. When you're cycling, the long sleeves and high collar will protect you from the sun, and the mesh panels will keep you cool. Note: Although the jersey has good UPF protection, don't forget to still take general sun - protection precautions. Avoid sharp objects that could damage the fabric. Maintenance: You can machine - wash the jersey in cold water with mild detergent. Don't use bleach. Tumble dry on low or hang it to dry. This will help keep the jersey in good condition and maintain its performance.
