Comfortable and casual still means mega fashionable with these adidas by Stella McCartney track pants. They have a regular fit, but depending on what you do with the zips on the sides, you can play with the shape and open them up. The knit material feels nice against the skin, and the durable water-repellent makes sure the wet stays where it should — outside. This product is made with 100% recycled materials. By reusing materials that have already been created, we help to reduce waste and our reliance on finite resources and reduce the footprint of the products we make.
