The KÜHL AIRSPEED™ LS Shirt is a game changer. Hot sun, high humidity, and stifling air are no match for KÜHL's collection of AIRSPEED™ shirts with AirVolution™ fabric. AirVolution™ is a woven, technical nylon/poly blend that blocks the sun's harmful UV rays, wicks moisture and dries quickly. It feels like cotton against the skin but boasts all the performance of polyester.The AIRSPEED LS™ features a button-down collar, button front, adjustable cuff and 2 button-down chest pockets. A zippered security pocket is hidden inside the shirt at the chest, and a built-in custom sunglass cleaner is sewn inside the bottom left placket.
