To use this Women's Summer NS Skin Layer, simply put it on as your first layer before you go out for a ride. It's designed to fit snugly against your body, so choose the right size for the best comfort. When it comes to maintenance, you can machine - wash it in cold water. Use a gentle detergent to keep the fabric in good condition. Avoid using bleach or fabric softeners as they may damage the special yarns. After washing, lay it flat to dry. This will prevent any stretching or distortion. Make sure to check the label for any specific instructions. With proper care, this layer will keep you cool and comfortable for many rides to come.
