Rambler 20 Oz Tumbler Ms

YETI Rambler® 20 Oz Tumbler is made of durable stainless steel with double-walled vacuum insulation to keep your drinks always hot or cold. The included lid with MagSlider ™ technology adds an extra barrier of protection to maintain internal temperature and prevent heat and cold from escaping (the slide magnet closure is not watertight and does not completely prevent spills).
