Mesa Loop with Covered Straw

The airflow relief valve is a game changer—I don't have to suck nearly as hard to get a sip, and the wider contoured straw feels way more natural. The twist-in lock keeps the straw perfectly in place even when I toss it in my bag, which is exactly what I needed.

I was skeptical about the twist-in locking straw at first, but it stays put perfectly even when I toss the cup in my bag. The wider contoured straw really does make sipping effortless, especially with thicker smoothies.

The airflow relief valve really does make a difference—sips come through smoothly without that annoying suction struggle. The contoured straw's wider mouth feels oddly natural, like drinking from a proper cup. My new go-to mug for morning coffee.
