SEALS YOUR DRINK TO KEEP SPLASHES AT BAY WHILE ON THE GO. 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 — any drink you’re craving — contained while helping prevent heat or cold from escaping.
