Introducing the TYR Airtec Tee. The tee that disappears when you need it to. At 145gsm, the Airtec is built to be felt as little as possible — ultra-soft cooling fabric that sits against the skin without friction, without weight, without distraction. The athletic fit moves non-restrictively with the body through every plane of motion, while chafe-free construction at the arms and neckline eliminates the points of contact that break focus mid-session. Moisture-wicking and quick-dry fabrication pulls sweat away and resets fast, so the tee keeps pace no matter how hard the work gets. Clean lines. Zero interference. This is what a training tee is supposed to feel like.
