On Prism Collection

Performance shouldn't come at the cost of practicality. And the Performance Tights are here to prove it. A preshaped silhouette with a bonded design is engineered to especially fit your moving body. And the cord around the waistband allows you to create your own personalized fit – everything you need to get (and stay) moving. But you don't have to run without your valuables. Use the zipped back pocket and the side pocket to store your keys, credit card or even your phone. To ensure lasting comfort, we chose a silky-smooth fabric that features a moisture-wicking treatment. This way, the exceptional feeling of those first miles remains throughout every run.

Product Highlights

Adjustable Fit. Create your own personalized fit with the adjustable waistband.
Integrated Pockets. Choose between the zipped back pocket or the large side pocket to bring your your keys, credit card or phone.
Premium Engineering and Materials. Preshaped for movement, premium engineering plus a smooth, moisture-wicking fabric creates next-level comfort.
