The Rambler? 10 oz (295ml) Lowball is made with YETI?'s tried and true double-wall insulation to be the ideal drinking companion. It will keep your hot drinks hot and your cold drinks cold longer than standard drinkware so you can enjoy everything from your evening drink by the fire to your coffee the next morning. Like the entire Rambler? Family, your Lowball and its lid are dishwasher safe for easy cleaning. Standard Lids come included with the Lowball, but it also works well with the MagSlider? Lid.
