To use this sweatshirt, simply put it on and enjoy its cozy warmth. When it comes to care, remember not to wash it for at least ten days after it's shipped because of the anti - fraying treatment. Once it's time to wash, follow the regular washing instructions for cotton - polyester blends. You can machine - wash it on a gentle cycle with similar colors. Hang it to dry to maintain its shape. Since it's a made - to - order item, be patient as it takes 7 - 10 business days to process. And don't worry about pills as it's made of NuBlend® pill - resistant fleece. Just wear it, have fun, and keep warm!
