كوب كلاسيكي

I've left this tumbler in my car during a summer afternoon and the ice was still clinking when I came back. The outside stays completely dry too, no more condensation rings on my desk.

The straw lid snaps on tight enough that I can toss it in my work bag without a second thought, and the double-wall insulation means my tea is still steaming at lunch. The outside stays perfectly dry even with hot liquid inside, which is exactly what I needed.

The straw lid snaps on tight enough that I finally trust throwing this in my tote bag without a leak. Double-wall insulation does its job—my iced coffee stayed cold for a solid workday, though the lid could use a bit more seal around the straw hole. Solid pick if you're tired of sweating cups.
