Magslider lidthe MagSlider Lid means enjoying a hot drink from our Rambler Tumblers without worrying about splashes on the go. Unlike other Closeable drink lids, Ours harness the power of magnets (Yep, real magnets) for smooth opening and closing, and has a crystal Clear lid so you can always see if you’re in need of a top off. Our magnet technology also makes for easy cleaning — you can pop the MagSlider off, rinse, dry, and return it to the YETI slider lid. And the MagSlider Lid is spill- and shatter-resistant, just like the rest of our Rambler accessories. Dishwasher-safe.
