To use this tee, simply put it on like any other shirt. It's great for casual wear or for your bike rides. When it comes to washing, you can machine wash it in cold water. Avoid using bleach as it may damage the fabric and the colors. Tumble dry on low to keep the shape and softness of the tee. If you want to iron it, use a low - heat setting. Also, don't wring the tee too hard when taking it out of the washer to prevent any stretching.
