To use this sweatshirt, simply put it on and enjoy the cozy warmth it provides. It's great for casual outings, lounging at home, or as a layer under a jacket in colder weather. As for care, it's best to machine - wash it in cold water with like colors to keep the colors vibrant and the fabric in good shape. Use a gentle cycle to avoid any damage to the heat - transfer design. Tumble dry on low to prevent shrinkage. Since it takes 7 - 10 business days to process, please be patient when placing your order. And remember, the NuBlend® fleece is pill - resistant, but still handle it with care to maintain its quality over time.
