The O2 Run Short Lined 5in

Formally the Infinite Short. Engineered for speed, breathability, and movement. With 360° ventilation, mesh panels, a sleek drape, and smart storage (including a hidden zip pocket), they’re built to run, made for beyond.

Built to perform. EveryWear's weightless, no-frills construction disappears on your body so you can push harder, move faster, go longer. Four-way stretch moves in every direction, and sweat-wicking tech handles high-intensity output from start to finish.
