Description
The YETI Rambler 20 oz Tumbler is the size most people reach for first, big enough for a full morning coffee or a pint of ice water and narrow enough to sit in a standard cup holder. The 18/8 stainless steel body and double-wall vacuum insulation hold temperature through a long drive or a full day on the water, and the No Sweat exterior keeps condensation off your hands and off the boat deck.
It ships with the YETI MagSlider Lid, a magnetic slider that closes the drinking opening between sips to slow heat transfer and cut down on splashing. The lid and the tumbler are both dishwasher safe, and the DuraCoat finish on the colored versions resists peeling and cracking.

Why We Like It
The 20 oz is the tumbler that gets used every day rather than the one that lives in a cabinet. It holds enough to be worth filling, fits the cup holder in a truck or a skiff, and the MagSlider lid is the part that makes it work on the move: the magnet is strong enough to stay put over rough water but light enough to slide open one-handed while you are holding a rod.
Insulation performance is the real reason to spend up here. Ice put in at the launch is still there at the takeout, and hot coffee poured before dawn is still hot mid-morning. Because the whole unit goes in the dishwasher, including the lid, it stays in rotation instead of becoming a project to clean.
