Our AirFit Muscle Shirt works as hard as you do. The special piqué knit weaves micro fibers into a strong yet astonishingly soft fabric. A fabric that will absorb and disperse 50% more moisture than cotton. And, unlike most performance underneath wear, AirFit naturally provides antibacterial and anti-odor properties. So hit the gym, run the route or head to the office knowing your underwear is as comfortable and as confident as you are. Air Fitness muscle shirts offer superior comfort and can be worn on their own or as a base layer.
Sophisticated piqué knit for high comfort and high performance
