From Tekno RC:
Our newest addition to our shirt line includes a horizontal stylized logo across the front and a new star “T” logo on the back. These shirts were made for hotter weather. They are 50% cotton/50% polyester and super light weight. By far the most comfortable shirt in your drawer. The printing is done with a special fade resistant ink that makes the printing feel soft almost as if it’s part of the shirt itself. They come in a new graphite heather color and are sold in sizes S-XXXL.
