The YETI Rambler Tumbler MagSlider Lid 10oz/20oz means enjoying drinks from YETI's Rambler® Tumblers without worrying about splashes on the go. Unlike other closeable drink lids, this harnesses 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. YETI's 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.
