No workout wardrobe is complete without these hyper-functional and ultra-stylish tights. The adidas by Stella McCartney performance focus is evidenced in the tights’ COLD.RDY technology, which was designed to insulate your body and keep you warm as the temperatures start to drop. The adjustable tie cord at the waist gives you a secure fit, and you can easily stash your cardholder and keys in the zipped pocket on your next outdoor run. Crafted from recycled polyester and shaped for a flattering mid-waisted and figure-hugging silhouette, they offer optimal coverage and support for all manner of workouts. Coordinate them with the TruePace High Support Bra for your next high-impact session.
