YETI 2 Stackable Thermal Mugs 177ml Rambler 'Navy'

Frequently asked questions

• How many ml does the 6 oz YETI Stackable Mug hold?

  The YETI Stackable Mugs have a capacity of 177 ml. This is exactly the right size for a flat white, cortado or a double espresso with some extra room. Not for big coffee, but for good coffee.

• Why are YETI Stackable Mugs sold in sets of two?

  Because good coffee isn't just for drinking alone. YETI sells them as a set of two so you always have one for someone else, or a spare if one is in the dishwasher.

• Do YETI Stackable Mugs come with a lid?

  No, the mugs are supplied without a lid. If you'd like one, the small MagSlider™ lid will fit. This is available separately. Please note: this lid is not leak-proof, but it does retain heat longer.

• What exactly is the DuraSip™ Ceramic coating?

  It has a ceramic interior that is directly applied to the stainless steel inner body. It gives you the feel of a regular ceramic mug, but one that will survive a fall from the camping table. Coffee stains do not penetrate, and cleaning is easy.

• Do YETI Stackable Mugs keep coffee warm?

  Yes, but not for as long as a larger YETI. Due to its smaller size, it has less insulating capacity. If you drink it quickly, that's not a problem. If you want to keep the coffee warm for longer, use the MagSlider™ lid and pre-warm the mug with hot water before pouring.

• Do YETI Stackable Mugs fit under my espresso machine?

  In most cases, yes. The mugs are low enough to fit under most espresso machines. If you have a machine with a very low spout, please check the height. The mug, including the handle, is slightly wider than a standard espresso glass, so also pay attention to the width of the spout.

• Can I also put tea or other hot drinks in it?

  The mugs are not exclusively for coffee, even though they are optimized for it. Tea, broth, hot chocolate – it doesn't matter. The ceramic interior does not absorb odors or flavors from previous drinks.

• Are the YETI Stackable Mugs dishwasher safe?

  Yes. All YETI Rambler products are dishwasher safe. If you prefer to wash them by hand, warm water with dish soap is sufficient. Do not use bleach or abrasive cleaning agents.

• Are YETI Stackable Mugs microwave safe?

  No. Stainless steel and microwaves don't mix. Never put them in the microwave, and never put them over an open flame or other external heat source. This can damage the vacuum insulation.

• Can the ceramic coating wear off or peel?

  Not with normal use. The DuraSip™ Ceramic coating is scratch-resistant and directly fused to the stainless steel; it's not a loose layer that will come off over time. However, you should avoid metal cutlery or stirrers scraping along the inside, as this can eventually damage the coating. If you just use it for coffee or tea and wash it in the dishwasher, it will last a long time.

• Is the handle of the YETI Stackable Mugs sturdy enough?

  Yes. The handle is welded all around the mug, not clipped or screwed. YETI itself calls it a "360-degree welded handle" and it's designed not to break off even if dropped. That's exactly the difference compared to a regular ceramic mug.

• Are YETI Stackable Mugs BPA-free?

  Yes. All YETI Rambler Drinkware is BPA-free.

• Do YETI Stackable Mugs come with a warranty?

  Yes, five-year warranty. That applies to all YETI stainless steel drinkware.

• What is the difference between YETI Stackable Mugs and a regular ceramic espresso cup?

  A regular ceramic mug cools down quickly, breaks when dropped, and isn't taken outdoors. YETI Stackable Mugs keep your coffee warm longer, survive a beating, and are just as easy to take camping as they are to use on your kitchen counter. The DuraSip™ coating gives you the familiar feel of ceramic, but in a mug you'll still be using in five years.
