Riley L. ★★★★★

I've tipped this over in my bag twice and not a single drop leaked, which is more than I can say for my old cup. The double-wall vacuum keeps my coffee hot for hours, and it fits perfectly in my car's cup holder.

Victoria F. ★★★★★

The lid seals tight enough that I stopped worrying about spills in my bag, and the vacuum insulation keeps my iced tea cold through a full work shift. The 18/8 steel body feels solid but light, and it slides right into my car’s cup holder. Honestly, it’s become the only cup I grab anymore.

Joshua O. ★★★★★

Took my usual commute coffee on a bumpy train ride and not a single drop escaped through the lid, plus it still held warmth for hours. The 18/8 steel feels solid without weighing my bag down, and the slim shape slides right into the car's cup holder without wobbling.
