Keep splashes at bay and debris out with the Rambler® MagSlider™ Lid — individually sized for YETI Mugs, Tumblers, and Lowballs. 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. Please note: the MagSlider Lid is not leakproof and will not prevent spills. Fits 295 ml Lowball, 295 ml Mug, 710 ml Mug, 473 Stackable Mug, 591 ml Tumbler Details Dishwasher Safe: Because no one needs more work to do. Magnets: Makes for easy opening and closing.
