Mesa Loop med täckt sugrör

The straw twists in and locks so it doesn't pop out when I'm carrying it around, which was my main annoyance with my old cup. The wider opening really does make sipping easier, though I still tip it a bit far sometimes. Solid everyday water bottle.

The airflow relief valve makes such a difference — no more fighting to get a drink out of a covered straw. The contoured straw is wide enough that I actually finish my whole glass of water without thinking about it.

The twist-in locking straw is the feature I didn't know I needed — no more pulling the straw out by accident mid-sip. The airflow valve really does make drinking feel effortless compared to my old tumbler.
