Utah Thin Blue Line Shirt featuring Utah with a Thin Blue Line. We print this design on the American Apparel t-shirt because it is the smoothest and softest t-shirt you’ll ever wear. Made of fine jersey, it has a durable, vintage feel. These classic-cut shirts are known for their premium quality, as well as ability to stand up to a washing machine (will keep size and color after many washings). The shirts are 100% fine jersey cotton. Great Police Gift for Utah Police Officers, Utah Police Wives, Utah Police Supporters, Utah Residents, and fans of Thin Blue Line Shirts.
