Small, light and graceful, but surprisingly roomy considering its appearance. Keeps both heat and cold inside really well. In every way, the best mug I've come across.

Double wall steel mug - this keeps your drinks that much warmer. Let’s face it - when you’re out there during the cold season, your mocca / chocolate milk / tea gets cold really, really quickly. This mug helps a great deal: it keeps your drink warm longer.
