It's finally Prime Day (opens in new tab). For the next 48 hours (or until 12am PST on October 14), everything from AirPods (open in new tab) to Dutch ovens to fashion is on sale.

Core10 (opens in new tab), an Amazon brand that until recently was well known among athleisure enthusiasts with a knack for thrifting, is now offering some of its best-selling leggings for as low as $20. It is not clear when Amazon began specializing in leggings, but many reviewers have praised Core10's styles as comparable to those of Lululemon.

This see-through, stretchy style boasts nearly 700 reviews with an average rating of 4.5 stars.
