The YETI Rambler Lowball 10 oz with Magslider Lid is the ideal drinking companion. The Lowball's double-wall vacuum insulation will keep your hot drinks hot, and your cold drinks cold longer than standard drinkware. Enjoy your evening drink by the fire, and refill with coffee the next morning. Like the entire Rambler Family, the Lowball and included MagSlider Lid are dishwasher safe for easy cleaning. While the magnet on this fan-favorite lid adds an additional barrier of protection to keep drinks contained and prevent heat or cold from escaping, please note this magnet component is not leakproof and will not prevent spills.Features18/8 stainless steel Double wall vacuum insulation Dishwasher safe
