The YETI Rambler 10 oz Stackable Lowball is the ideal drinking companion. The Lowball is classic and versatile, ready for a morning camp coffee, neat evening bourbon, or any of your favorite beverages. Easy to stack and store, the Lowball's double-wall vacuum insulation will keep your hot drinks hot, and your cold drinks cold longer than standard drinkware. Like the entire Rambler Drinkware Family from YETI, the Lowball and included Magslider Lid are dishwasher safe for easy cleaning. While the magnet adds an additional barrier of protection to keep drinks hot or cold, this magnet slider is not leakproof and will not prevent spills.
