42KM Engineering
At 42KM, our dual expertise as runners and engineers fueled our ambition to design a tank that is both ultra-lightweight and incredibly soft on the skin. To achieve this, we meticulously selected the lightest fabric available and innovatively eliminated all stitches. The result is the Performance Tank, a garment that excels in both function and style.
