The YETI Rambler 10 oz. Lowball 2.0 is the perfect beverage companion. Its stackable design and double-wall vacuum insulation provide longer-lasting hot and cold drinks compared to regular drinkware. Savor a whiskey by the fire and refill with coffee the next morning. Both the Lowball and Magslider™ Lid are dishwasher safe for easy maintenance, with the lid's magnet adding another layer of insulation. Please note that the magnet slider is not leakproof and may not prevent spills.
