Mesa Loop med lokk og sugerør

The twist-in locking straw is the standout feature for me—it stays firmly in place no matter how much I toss the cup in my bag. And that contoured mouthpiece really does make sipping feel effortless, like I barely have to think about it.

The airflow relief valve makes sipping feel effortless—no more noisy gulping or having to tilt the cup way back. Huge upgrade from my old bottle, and the wider straw opening really does cut down on the suction effort.

The twist-in locking straw is a nice touch — it stays put even when I toss the cup in my bag. I just wish the lid seal were a bit tighter; a tiny drip escapes if I tip it too fast.
