Nike 2011 World Series Long Sleeve Undershirt, in the base color of that year's American League Champion Texas Rangers. This is the style, or one of the styles, the Rangers wore under their uniforms in that year's classic World Series against the eventual champion St. Louis Cardinals. Material is a thicker, heat gear type of material, and is size XL, but runs a bit small in my estimation. There is one small spot on the bottom right hand corner which will probably come out with a wash, but as I'm just trying to empty out one of the closets, I'm listing it as is. Item has been kept in a smoke free home.
