The Rambler 10 oz. Lowball is the ideal drinking companion. The Lowballs 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. Then throw your Lowball in the dishwasher, lid and all Standard Lids come included, but it also pairs well with the MagSlider Lid, so you can add it at any time.
