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.
