On Men's Race Singlet

A soft, ultralight racerback with next-level breathability for racing and training without limits.

Unbeatable breathability

Our athletes asked. And we delivered. With fewer contact points, the singlet's pleated construction feels cool and light on the skin, while offering exceptional breathability.

Almost weightless

Combining perforated and pleated fabrics, the Race Singlet feels almost weightless when worn. Bonded seams at the arms and neck mean next-level comfort and a distraction-free fit.

Fashion-inspired fabric

The pleated plissé fabric combines high-performance properties with an elevated aesthetic. For a unique look and textured feel that turns heads.
