Introducing Tracksmith X J.Crew, a new collab to help you hit the ground running. We partnered with the Boston-based brand on a capsule of high-performance gear in exclusive colors that can be mixed and matched with our own activewear—for training, racing or taking a rest day. These joggers are made with ultradurable, water-repellent fabrics in a tapered fit. Plus, they're complete with stirrup details to keep them in place and zippers at the backs of the ankles for maximum comfort and functionality. Get the set: Pair it with the matching sweater.
