Mesa Loop 附蓋吸管杯

I usually finish a whole tumbler in ten minutes, but this straw slowed me down in a good way. The twist-in locking straw hasn't popped out once, even when I knocked the cup over on my desk.

I didn't expect the twist-in locking straw to make such a difference, but it stays put and I never have to fish it out. The contoured tip is wider than my old cup's straw, so sipping takes way less effort, and the big opening means I actually drink more water during the day.

The airflow relief valve actually works, no more fighting to get a drink through the straw. I've been using it for my morning iced coffee and the wider straw opening makes sipping effortless.
