Dress shirts are dress shirts, right? Wrong. The Phenom Professional Light Blue Long Sleeve Men's Dress Shirt marries a 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.
