Warp-knit polyester long sleeve football referee shirt with the Illinois IHSA logo embroidered above the pocket. Option to add the IHSA Official logo to the left sleeve. The ComfortTech technology provides a moisture wicking-anti wrinkle durable referee shirt. Wear this shirt with just a t-shirt underneath for those moderately cool games, or layer up for the cold Friday nights. The extended tail on the Smitty's shirt will stay tucked in to keep a tailored look and eliminates the need for additional length shirts. All Smitty Apparel products are designed by one of the top officials in the world, for officials.
