The 25oz size is perfect for my whole workday—I fill it once in the morning and it’s still cold by late afternoon. The lid seals tight enough that I can toss it in my bag without a single leak, which is a huge win for me.

I was skeptical about how long it would actually keep my iced coffee cold, but six hours later there was still ice clinking around. The 25oz size is perfect for my whole morning commute without needing a refill.

Took this tumbler on a road trip and it held up perfectly, the 25oz size is just right for the car cup holder. Ice was still clinking around hours later, which surprised me given how hot it gets in the sun. Solid lid too, no leaks even when it tipped over on the passenger seat.
