Klassieke Tumbler

Brought this to my desk job and the straw lid is a lifesaver—no spills when I knock it over. The double-wall insulation keeps my iced tea cold through an entire afternoon of meetings, and the outside stays dry, which my paperwork appreciates.

It's 8pm and my coffee is still warm from this morning, which has never happened with any other cup I've owned. The outside stays completely dry even with ice inside, and the straw lid has survived being thrown in my work bag every day for a month without a single leak.

I’ve been leaving this in my car during summer errands and the double-wall insulation really does keep my water cold for hours—no condensation on the outside either. The straw lid clicks on tight enough that I can toss it in my bag without worrying about leaks.
