Dress shirts are dress shirts, right? Wrong. The Phenom Professional White Long Sleeve Men's Dress Shirt, marries carefully thought out design with performance materials. Made of a special stretch blend of recycled polyester and a high percentage of spandex, this dress shirt feels more like a workout top than a stuffy collared shirt. This specialty blend also allows us to use a special heat-setting process known as fiber shape retention, which makes the shirt wrinkle resistant.  Each shirt is also treated with our specially formulated DWR (Durable Water Repellent) coating, which gives them premium properties of liquid, odor, and stain resistance.
