You get to choose from either the 20 oz. or 24 oz. model in for this deal, though only in one color. When we post deals on these mugs, it’s usually the West Loop model, but the Byron’s a little bit different. Unlike the West Loop, the Byron’s lid doesn’t open and close automatically, though many reviewers say it’s easier to clean. The Byron also includes a rubberized non-slip sleeve, which is a nice touch, especially at these prices.
