The Tumbler | 10oz is exactly what I needed for my morning espresso. Triple-layer insulation keeps drinks hot for a good while, and the splashproof slide-open lid means no leaks when I toss it in my bag. It fits perfectly in my cup holder, which is a big plus for commuting. The compact size is great for tea or iced coffee too. Only minor thing: 10oz goes fast if you're a heavy coffee drinker, but for a quick fix it's ideal. Solid little tumbler.
