The Rambler® 295 ml / 10 oz Lowball 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 drinkware. Enjoy your evening whiskey by the fire, and refill with coffee the next morning. Like the entire Rambler Family, your Lowball and its lid are dishwasher safe for easy cleaning.
