At Perdu we’ve created this comfortable invisible undershirt for bussinesmen. Our shirts are tight cut and skin toned so you can wear them under any slim-fit shirt without someone noticing the sleeves or collar. They are made of a well balanced combination of elastane and lyocell. A fabric that feels comfortable, light and is very breathable. You almost don’t even notice that you are wearing an undershirt. This invisible undershirt can be worn under any of your favorite shirts and protect it from sweat stains.
