How to use: Simply put on this base layer before your cycling ride. It can be worn directly against the skin. Remember to choose the right size for a snug fit. Notice: Avoid sharp objects that might tear the mesh fabric. If you have sensitive skin, do a patch test first. Maintenance: Wash it in cold water with mild detergent. Hang it to dry to maintain its shape and fabric quality. Don't use fabric softeners as they may reduce the fabric's moisture - wicking ability.
