The Rambler 10 oz (296 ml). Lowball is the ideal drinking companion around the campfire. Whether it replaces your morning coffee cup or serves as your nightly whiskey glass, the Lowball's double-wall vacuum insulation will keep your hot drinks hot and your cold drinks cold far longer than standard drinkware. And unlike your favorite bourbon glass, this Lowball will never shatter or leave a ring on your coffee table, thanks to its 18/8 stainless steel construction and No Sweat Design.
