The lid seals tight enough that I can toss it in my bag without worrying about spills, and the straw makes sipping easy. I like that it handles both hot coffee and cold water, though hand washing is a small price to pay for how solid it feels.

My iced coffee stays cold for hours in this 20oz tumbler, and the lid snaps on tight enough to toss in my bag without a drop leaking. The straw is long and clear, which makes it easy to see when I need a refill.

The clear straw is a nice touch—it fits snugly in the lid and makes sipping cold water on my desk feel less awkward. Ice stays solid for hours, and the 20oz size is perfect for my afternoon refills.
