Calvin Klein Performance - Calvin Klein’s athleisure line combines performance materials with the label’s fashion-forward design aesthetic, seen here with these navy track pants. Crafted from mid-weight shell with a breathable mesh lining, they are punctuated with a logo-embossed stripe down one leg and elasticated cuffs in a nod to classic jogger silhouettes. Pair with a coordinating shell jacket and statement trainers for an active afternoon.
