The Rambler® 10 oz. Lowball will keep your iced beverage cold and the ice clinking. The Lowball’s is designed with a double-wall vacuum insulation to keep your hot drinks hot or cold longer than standard drinkware. Enjoy an evening Irish Coffee by the fire, and refill with coffee the next morning. The Lowball and its lid are dishwasher safe for easy cleaning. Standard Lids come included the Lowball, but you may want to upgrade with the MagSlider™ Lid, so you can add it at any time.
