What it does
A 14 ounce double-wall vacuum insulated stainless steel coffee mug with a handle and a magnetic sliding lid.
- Vacuum insulated walls keep coffee hot and cold drinks cold
- Magnetic slider opens with one hand and pops off the lid for cleaning
- Wide opening, roomy enough for a foamy latte
- Mugs nest inside each other for cabinet storage
- YETI's current 14 oz stackable version adds a DuraSip ceramic lining inside
A good pick for someone who wants a full size coffee that stays hot at the desk or around camp, and who will run it through the dishwasher daily. The trade-offs are weight, a lid that is splash resistant but not leakproof, and a price well above an ordinary mug.

Questions
Is the YETI Rambler 14 oz mug lid leakproof?
No. The product copy on the Murdoch's listing says the MagSlider magnet is not leakproof and will not prevent spills. YETI calls it splash resistant.
Is the YETI 14 oz mug dishwasher safe?
Yes. Both the mug and the MagSlider lid are dishwasher safe.
Can a YETI mug go in the microwave?
No. It is stainless steel, and the product copy also says not to place it over a heat source or open flame.
How long does the YETI 14 oz mug keep coffee hot?
In a Yahoo Shopping test with the lid on, water poured at 179°F was 157°F after 30 minutes and 149°F after an hour. That test used the current ceramic lined version.
Does the YETI 14 oz mug fit in a car cup holder?
Bustle's reviewer found it does not fit standard cup holders, so it works better as a home or camp mug.
