How to use: Simply put on the jersey before your mountain biking trip. It's designed to fit comfortably over your base layers. Attention: Avoid sharp objects that may tear the fabric. When washing, turn it inside out to protect the color and fabric quality. Maintenance: Wash it in cold water with a mild detergent. Hang it to dry instead of using a dryer to prevent shrinkage and damage to the fabric. This way, your jersey will stay in good condition for many rides to come.
