The Quencher H2.0 FlowStateTM Kelímek | 20 OZ

The cup holder fit is what sold me, and it’s held up perfectly next to my desk all week. Ice cubes are still clinking around hours after I filled it, and the straw lid seals tight enough that I can toss it in my bag without a leak.

I was skeptical about the whole straw-tumbler craze, but the 20 oz size is genuinely perfect for my desk—I refill it twice a day and the lid seals tight enough that I’ve knocked it over twice with zero spills. The straw is sturdy and the cup fits my hand better than any bottle I’ve owned.

The lid seals tight enough that I can toss it in my work bag without a single leak, and the 20 oz size fits perfectly in my car's cup holder. It keeps my water ice-cold from morning meetings straight through lunch.
