To use this tee, simply put it on and enjoy your day! The moisture - wicking feature makes it great for any activity, whether you're playing sports or just running errands. When it comes to washing, use cold water and a gentle cycle. Hang it to dry to keep its shape and the graphic looking sharp. Avoid using bleach as it might damage the fabric and the print. Also, don't iron directly over the graphic print to prevent it from peeling. With proper care, this tee will stay in good condition for a long time.
