To use this sweatshirt, simply put it on and enjoy the cozy warmth. When it comes to washing, use cold water and a gentle cycle to keep the design looking good. Avoid using bleach as it may damage the fabric and the heat - transfer design. After washing, tumble dry on low to prevent shrinkage. Store it in a cool, dry place to maintain its quality. And remember, since it's made to order, give it 7 - 10 business days to be processed before you can wear it.
