Let them play! Your kids will be so happy without being pulled and prodded at as they run around and play in this crewneck sweatshirt. They just want to be out there having fun, and you just want them to stay warm so you both win! The easy-to-care fabric is made of a cotton/polyester yarn that has been preshrunk, while the 1x1 rib knit cuff and hem has an added element of spandex to allow for easy movement and flexibility.
