The YETI Rambler 42 oz Straw Mug with Straw Lid is a resilient mug for all-day use. Road trips, classrooms, in the office, it's rarely out of place and always provides quick sips. The double-wall vacuum insulation keeps the drink ice-cold, and it's dishwasher safe at the end of the day. The lid includes a reusable straw, while the built-in handle makes it easy to lift towards your mouth.
