Zojirushi Stainless Mug vs YETI Rambler
Short answer: Buy the Zojirushi for a bag or a commute and the YETI Rambler for a desk. The Zojirushi SM-KHE is a sealed travel mug: a flip lid with a safety lock, and vacuum insulation Zojirushi rates at 154°F after six hours in the 16 oz size. The YETI Rambler 14 oz is a handled mug whose MagSlider lid YETI calls splash-resistant, not leakproof, but it goes in the dishwasher, which the Zojirushi does not.

Common questions
Zojirushi vs YETI: which is better?
It depends where the mug lives. For a commute or a bag, the Zojirushi SM-KHE: its lid locks shut, it scores 91 for heat retention and 86 for leak-proofing here against the YETI's 83 and 78, and Zojirushi publishes hold-time figures to back the heat claim. For a desk, the YETI Rambler 14 oz mug: it has a handle, sips like a regular mug through the MagSlider lid, and goes in the dishwasher.
Which keeps coffee hotter?
The Zojirushi, on published figures. Zojirushi rates the 16 oz SM-KHE48 at 187°F after one hour and 154°F after six hours, starting with 203°F water in a 68°F room, and cold drinks at 48°F after six hours. YETI does not publish a hold time for the Rambler mug, only that it is double-wall vacuum insulated, so there is no like-for-like number to compare.
Is the YETI MagSlider lid leak-proof?
No. YETI's own site states the MagSlider lid is splash-resistant, not leakproof, and that it will not prevent spills — even though some retail listings for the mug describe the lid as leak-proof. It copes with a bump on the desk, but the mug will leak if it tips over or goes in a bag. For a commute, the Zojirushi's flip lid with its safety lock is the safer choice.
Are they dishwasher safe?
The YETI is; the Zojirushi is not. YETI lists the Rambler mug as dishwasher safe. Zojirushi says its vacuum insulated mugs and all their components should be hand-washed with mild dish soap and a soft sponge, though the SM-KHE's stopper comes apart for cleaning and its SlickSteel interior is designed to resist stains.
Can I put a latte in the Zojirushi mug?
Zojirushi advises against it. Its FAQ says not to fill its vacuum mugs with drinks containing dairy, which can curdle and leave odors, or with carbonated drinks. Black coffee and tea are what it is designed for. If your daily drink is a latte, the dishwasher-safe YETI is the easier mug to live with.
Is Zojirushi a Japanese brand, and what does the name mean?
Yes. Zojirushi traces its roots to the Ichikawa Brothers Trading Company, founded in Osaka in 1918, which began making vacuum bottles in 1923 with an elephant trademark. The company took the name Zojirushi in 1961; Zojirushi explains that zo means elephant in Japanese. The SM-KHE mug itself is made in a Zojirushi factory in Thailand, per Zojirushi.
SM-KHE36 or SM-KHE48: which size should I get?
The SM-KHE48 is the 16 oz mug this page compares; the SM-KHE36 is the same design at 12 oz. Zojirushi lists the 12 oz at 7-3/8 inches tall and the 16 oz at 9-1/8 inches, with the same 2-5/8 by 2-7/8 inch footprint, and rates the smaller mug slightly lower for heat, at 147°F after six hours against 154°F. Both carry Zojirushi's five-year warranty on the vacuum insulation.
