Mitchell & Ness Throwbacks vintage retro style Pittsburgh Steelers long sleeved shirt. 100% cotton Rugby jersey type material (no collar); not a thin t-shirt. Quality and in excellent condition. Never worn. All items come from our own personal closet and have been purchased brand new by us. First time seller on Poshmark--just cleaning out our closets and not a professional flipper. Most items have barely been worn, if at all, and will indicate condition on each. Smoke free, clean home, but we do have two pups and a cat for those concerned with allergies. All items will be laundered.
