Stack Athletics is a pickleball and racket sport apparel brand based in Kaysville, Utah. Owned and operated by players, the company leans into pickleball’s reputation as a loud sport and builds pro level clothing for athletes who embrace it. The women’s line covers skorts, skirts, dresses, biker shorts, liners, bras, and tees, and there is a men’s tennis and pickleball collection as well. Recent lines have introduced house fabric technologies including the MellowMesh liner, the Flowstate blend, and the CaddyPocket, developed and tested through heavy on court play. Orders come with free 30 day exchanges and returns, and a store locator on the site lists retail shops that stock the brand for anyone who wants to try pieces on in person.
