Mesa Loop with Covered Straw

The twist-in locking straw is the standout feature for me—it clicks in securely with zero leaks, even when I toss it in my bag sideways. The contoured straw’s wider opening means I’m not sucking hard to get a drink, which makes my morning commute way less awkward.

The airflow relief valve really does make a difference—I’m not getting that annoying vacuum effect mid-sip, and the wider contoured straw means I barely have to tilt my head. It’s become my go-to for water at my desk.

The twist-in locking straw is such a game changer—no more fiddling with a loose lid or hunting for a stray straw in my bag. The wider contoured opening makes sipping feel effortless, and I love that it stays put even when I toss it in my tote.
