We built the Rambler 10 oz Lowball to be your all-day drinking buddy, from your first cup of joe to your last nightcap. Along the way, the double-wall vacuum insulation will keep your hot drinks hot and your cold drinks cold far longer than standard mugs or cocktail glasses. And unlike your favorite bourbon glass, this lowball will never shatter on impact or leave a ring on your coffee table thanks to its 18/8 stainless steel construction and No Sweat™ Design. Taking your beverage to go? Dishwasher safe. Lid not included.
