The MagSlider Lid means enjoying drinks 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 have 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 dishwasher safe and shatter-resistant， just like the rest of the Rambler accessories.
