To use this sweatshirt, simply put it on and enjoy the cozy warmth it provides. When it comes to care, it's best to wash it in cold water with like colors to keep the design and fabric in good condition. Avoid using bleach as it might damage the fabric and the heat - transferred design. Tumble dry on low to prevent shrinking. Since it's made to order, be patient during the 7 - 10 business - day processing time. When storing, fold it neatly to avoid creases. And remember, the spandex in the collar, cuffs, and waistband means it'll stretch and fit you comfortably, but don't over - stretch it to maintain its shape.
