On Running Performance-T Lumos: Lightweight, Breathable and Reflective for Every Run

Go for comfort as well as visibility with the Performance-T Lumos. This short-sleeve running shirt is made for fast miles and long endurance runs: ultralight, quick-drying and designed to minimize friction.

Innovative materials and seam finishes.

The On DryTec™ fabric breathes, wicks away sweat at lightning speed and dries quickly. The smooth bonded back hem and taped seams reduce friction, while contoured sleeves and forward facing side seams follow your natural arm swing. Result: minimal chafing, maximum focus.

Visible when it counts

Reflective details stand out subtly during the day and light up at dusk and dark-ideal for early starts, late finishes and everything in between.
