To use this sweatshirt, simply put it on like any other top and enjoy the cozy warmth. When it comes to washing, use cold water and tumble dry on low to keep the fabric and design in good condition. Avoid using harsh detergents as they might damage the heat - transferred design. Also, since it's made to order, please be patient during the 7 - 10 business - day processing time. If you notice any pills on the fleece over time, a fabric shaver can help keep it looking new.
