Keep splashes and dirt out with the Rambler® MagSlider ™ lid - individually sized for YETI mugs, cups, lowballs and stackable pints. The smooth magnet offers a reliable sliding mechanism for every size. Plus, the magnet is easy to remove for easier, more thorough cleaning, so it can stay in top shape and last far longer than other sliding lids out there. This dishwasher-safe lid also adds a protective barrier to keep coffee, water, wine and any drink you fancy in - while helping prevent heat or cold from escaping.
