Yeti's 10 oz. Rambler® Lowball is the ideal drinkwear choice whether enjoying whiskey by the campfire or cabin coffee the next morning. Double-wall vacuum insulation keeps hot drinks hot, and your cold drinks cold longer than standard drinkware. The MagSlider™ Lid is dishwasher safe for easy cleaning, and controls internal temperature no matter the outside weather. Please note — this magnet component is not leakproof and will not prevent spills.
