Mesa Loop med dekket sugerør

The airflow relief valve makes a noticeable difference — no more fighting to get liquid up the straw. The contoured opening is wider than my old cup's, so sipping takes barely any effort.

I didn't expect the wider straw opening to make such a difference, but sipping takes almost no effort now. The airflow valve keeps things flowing smoothly instead of that annoying gurgle I used to get. It's become my everyday cup.

Love that the straw actually twists in and locks, so it doesn't slide out mid-sip. The wider opening is easier on my mouth than my old cup, and I've been using it daily for iced coffee.
