The Topo Tee. A contour-map design pulled from the ground we cover — ridgelines, climbs and descents rendered as a topographical print.Cut from BreatheTech, our most breathable fabric yet at 110gsm. It's built to move air rather than trap it: an open, fine-gauge knit that lets heat escape as fast as you make it, sheds moisture quickly, and stays light on the skin even when you're working. The kind of tee you forget you're wearing on a warm evening session.A note on fit: BreatheTech runs slightly bigger than our other fabrics. That's deliberate — the extra room keeps the fabric off your skin so air can actually circulate. If you're between sizes, or you like a closer cut, size down. 110gsm BreatheTech — our most breathable fabric yet Open knit structure for maximum airflow Fast-drying and moisture-shedding Relaxed technical fit for airflow Topographical contour print Available in unisex and female fits, XS–XXL
