Our Sleeveless Polo features our patented Icefil technology fabric. It works by converting sweat to refrigerant; cooling your skin 3 to 5 degrees, allowing you to be cool, comfortable, and dry on the hottest humid days. This garment also has built-in UPF 50 sun protection, moisture-wicking, and anti-microbial properties. Wear the Sleeveless Polo to all athleisure activities!
