Performance Tee
At 42KM, our passion for running and engineering drove us to create a tee built for speed and elite performance. We used stitchless technology to eliminate traditional stitches, reducing irritation and maximizing comfort. The lightweight, stitchless fit delivers a nearly weightless feel for unrestricted movement. Crafted from our Airobic fabric, known for exceptional sweat-wicking, this tee keeps you dry and comfortable—making it a standout in our Performance line.
