The Rambler 10 oz 295 mL. Lowball 2.0 from YETI is the ideal drinking companion. Easy to stack and store the Lowballs doublewall vacuum insulation will keep your hot drinks hot and your cold drinks cold longer than standard drinkware. Enjoy your evening whiskey by the fire and refill with coffee the next morning. 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.
