The RamblerÂ® 10 oz. Lowball is the ideal drinking companion. The Lowballâ€™s double-wall 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 Family, the Lowball and included MagSliderâ„¢ Lid are dishwasher safe for easy cleaning. While the magnet on this fan-favourite lid adds an additional barrier of protection to keep drinks contained and prevent heat or cold from escaping, please note â€”this magnet component is not leakproof and will not prevent spills. Available in stainless and DuraCoatâ„¢ colours.
