Keep splashes at bay and debris out with the Rambler® MagSlider™ lid individually sized for YETI® mugs, tumblers, lowballs and stackable pints. For each size, the smooth magnet offers a reliable sliding mechanism. Plus, the magnet is simple to remove for easier, more thorough cleaning, so it can stay in its prime and far outlast any other slider lids out there. This dishwasher-safe lid also adds a barrier of protection to keep coffee, water, wine, shandies and any drink you are craving, contained while helping prevent heat or cold from escaping. The MagSlider™ lid is not leak-proof and will not prevent spills.
