Mesa Loop med täckt sugrör

The wider contoured straw really does make sipping effortless, even when I'm half asleep at my desk. The airflow valve keeps things flowing without that annoying gurgle, and the covered top means I can toss it in my bag without worrying.

The twist-in locking straw actually stays put, which is huge since I'm always knocking cups over on my desk. And that airflow valve makes sipping way less work than my old tumbler.

I didn't expect the contoured straw to make such a difference, but the wider opening really does mean I barely have to work to sip. The airflow valve keeps things moving smoothly too, no annoying suction feeling. Been using it daily for a couple weeks and it's held up great.
