The Yeti Rambler Lowball 10 oz is the ideal drinking companion at the deer lease or around the campfire. Whether itís holding your first cup of joe in the morning or that last nightcap, 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. If you want to take your Rambler Lowball with you on-the-go, just pop on a Rambler 10/20 oz lid (not included) and itíll be ready for whatever you have in store. Toss out all your koozies. You won't be needing them to help keep your drink cold when you have the 10 oz Yeti Rambler Lowball.
