We exclusively use Next Level brand premium athletic fit, ultra-soft 4.3 ounce 100% ringspun cotton t-shirts. Pre-shrunk. Double-needle stitching throughout and taped shoulder to shoulder for durability. 100% designed and printed in the U.S.A. by Downrange Apparel, no cheap iron-on graphics! Athletic fit, shirts will fit slightly more snug through the shoulders and chest. NEW! We offer the XXL size in the fitted style and now in a 5.3 ounce 100% cotton regular cut t-shirt for those who prefer a more relaxed fit. All shirts are preshrunk but t-shirt will shrink slightly with the first wash. To avoid any shrinkage, simply wash the shirt in cold water and air dry it the first couple times you wash it.
