Lowball 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 drink ware. 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 Mag Slider Lid, so you can add it at any time.
