Sport Chalet announced on Saturday that it is closing all of its stores and has stopped selling goods online. "While our online store is no longer available, all Sport Chalet stores will remain open for several weeks, offering customers the opportunity to use their remaining rewards and gift cards, and to take advantage of great sales," the chain says on its website. Michelle De Leon, a department head at the Sport Chalet in Lake Forest, said employees found out about the store closure through their general managers on Thursday.
