ميسا لوب مع شفاط مغطى

The twist-in locking straw hasn't popped out once, even when I've knocked the cup over on my desk. Sipping takes way less effort than my old straw cup thanks to the wider opening.

The airflow relief valve actually makes a difference — no more fighting to get liquid up the straw. I fill it before my commute and it's still cold by lunch. Sipping takes way less effort than my old tumbler.

The twist-in locking straw is the detail I didn't know I needed, it stays put and doesn't wiggle loose in my bag. Sipping through the wider contoured opening takes way less effort, which honestly surprised me.
