The verdict
Zojirushi's vacuum mug keeps drinks hot or cold for hours, with a tight flip-open lid and a safety lock that stops it opening in a bag, and a wide mouth that takes full-size ice cubes. The interior is SlickSteel so it cleans easily and never holds flavor. The benchmark commuter mug.

YETI Researched
Rambler 14oz Mug with MagSlider Lid
A nearly indestructible desk mug with a handle; YETI's own product page calls the MagSlider lid splash-resistant, so treat it as a desk lid rather than a leak-proof one.
