We have been developing this material and shirt pattern for the better part of 10 years. We NAILED IT! This is the softest that a micro polyester shirt can get. With added spandex for maneuverability, SWC is proud to offer the softest, and coolest fabric in the game. It features raglan sleeves with mesh insert for breathability. Longer sleeves with thumb holes to keep sleeves in place and protection. Higher neckline on the back for neck protection.
