The YETI Tumbler has a capacity of 591 ml (20 oz). That's enough for a large coffee, a generous portion of tea, or simply a good amount of water for on the go. For those who always find a small mug insufficient, this is the right size.

How many ml does the YETI Thermomug hold?

How does the StrongHold™ lid work?

The lid screws onto the mug and is then locked into place by two magnetic sliders. You open it by pushing the slider away, drink, and then slide it shut again. There are four positions to turn the lid, suitable for both right and left-handed users. The lock prevents the lid from falling off if the mug tips over.

Is the lid completely leak-proof?

No. The StrongHold™ lid is leak-resistant, not leakproof. If the lid is open and the mug tips over, liquid will escape. With the lid closed, it effectively contains liquids during normal on-the-go use. If you want a completely leakproof option, check out the YETI Rambler Bottles with the HotShot™ Cap or MagDock™ Cap.

Does the YETI Thermo Mug fit in a cup holder?

Yes. The bottom has a diameter of 7 cm and thus fits in most cup holders in cars, bikes or boats. The handle does protrude slightly, so please check if there is enough space in your holder.

Can I also use the YETI Thermomug for cold drinks?

Yes. The double-wall vacuum insulation works both ways; cold drinks stay cold, hot drinks stay hot. Plus, the No Sweat™ coating keeps the outside dry, even with ice water inside.

How long does my coffee stay warm in the YETI Thermo Mug?

YETI does not specify exact hours, but in practice, coffee in the YETI Thermo Mug stays warm for several hours. If you pre-warm it with hot water and open it as little as possible, you will retain the heat for the longest time. Most users are still satisfied with the temperature after a workday.

Is the YETI insulated mug lid also suitable for other YETI products?

No. The StrongHold™ Lid was specifically designed for the YETI Rambler 20 oz Travel Mug and does not fit other Rambler Drinkware models. Other YETI Lids also do not fit the Rambler 20 oz Travel Mug.

Can I put sparkling water or soda in the YETI Thermomug?

No. The YETI Rambler Mug is not suitable for carbonated drinks. The pressure built up by carbonation can cause problems with the lid. Also, do not use it for storing food or perishable goods.

Is the YETI ThermoSense Mug dishwasher safe?

Yes. Both the mug and the lid are dishwasher safe. YETI recommends placing lids on the top rack and the gasket and MagSlider in the cutlery basket. If you prefer to wash it by hand, warm water with dish soap is sufficient.

Can the YETI mug be microwaved?

No. Stainless steel and microwaves don't mix. Never put it in the microwave, and do not place it over an open flame or other external heat source.

How durable is the DuraCoat™ color?

The DuraCoat™ coating does not discolour, flake or crack. It is not a paint but a baked enamel coating designed for daily use, including in a car, backpack or workshop. Beads on the steel under the coating are not to be expected with normal use.

How heavy is the YETI Thermo Mug?

Empty, it weighs approximately 530 grams. Filled, it comes to over a kilogram. The handle is 360-degree welded, making it easy to carry, even with one hand on the go.

Five years. This applies to all YETI stainless steel drinkware.

Is the YETI Thermomug suitable for children?

The StrongHold™ lid fits securely enough not to easily leak if a child knocks it over. Do not use it for children with very hot drinks, as the mug itself hardly gets warm on the outside, but the contents can still be quite hot.

Product information

The YETI Rambler® 20 oz Travel Mug is made for those who like to take their coffee or tea on the go. Thanks to its clever design, this travel mug fits in most cup holders, while the elevated handle ensures a comfortable grip. Whether you're commuting to work, embarking on a long road trip, or simply want to keep your morning coffee warm longer, this mug is built for everyday use.

This YETI Rambler® Travel Mug features the Stronghold™ Lid, a leak-resistant upgrade with dual-slider magnet technology. As long as the lid is properly closed, your drink is better protected against leaks and spills on the go. The lid is also rotatable and has multiple placement options, making it comfortable for both left- and right-handed users. Good to know: the Stronghold™ Lid is specifically designed for the YETI Rambler® 20 oz Travel Mug and does not fit other Rambler® models.

As you would expect from YETI, this Rambler® mug is also made from high-quality 18/8 stainless steel. This makes it resistant to rust, punctures, and intensive daily use. The double-wall vacuum insulation keeps hot drinks hot longer and cold drinks cold longer, so you can always enjoy your beverage at the right temperature on the go. After use, the mug can simply go into the dishwasher, making it extra practical for everyday use.
