Yeti has built the Rambler 10 oz. Lowball Tumbler 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 ceramic mugs or glass drinkware. And unlike your favorite old fashioned glass, this tumbler will never shatter on impact or leave a ring on your table thanks to its 18/8 stainless steel construction and No Sweat™ Design. Taking your beverage to go? Pop on the see-through Rambler lid to avoid splashing your beverage. Dishwasher-safe.
