We hope you are wearing your shirts outside. They are meant to get dirty, so we made sure that we used all washable fabrics, including our cotton flannel and our washable elbow patches. We do use 100% cotton, so your shirt will shrink. If you like the fit as is, before wash, we recommend washing in cold water and hang drying. If your shirt could shrink a bit, wash in warm water and tumble dry low or medium.
