To use this tee, simply put it on and enjoy the comfort all day long. For washing, use a gentle cycle in cold water to keep the colors and shape. Avoid using bleach as it may damage the fabric. Hang it to dry or tumble dry on low. If you need to iron, use a low - heat setting. This tee is very durable, but try not to pull it too hard to prevent any tearing. With proper care, it will last you a long time.
