Upgrade your Rambler tumbler with this Magslider spill-proof lid from YETI®. The Magslider features magnets for smooth opening and closing and stays securely closed if tumbler is knocked over in the boat, car, or at home. YETI's magnet technology works double-duty, allowing for easy cleaning. Simply pop the Magslider off, rinse, dry, and recap your tumbler. The clear lid lets you see when you need to top off and, like the rest of the Rambler series, the Magslider lid is spill resistant, shatter resistant, and BPA-free. Imported.
