Trek Pivot Tumbler

I was skeptical about the lid mechanism at first, but swapping between the straw and chug pieces is actually super smooth and hasn't leaked once. The stainless steel keeps my coffee hot for hours, exactly what I needed for long workdays.

I’ve been using this tumbler daily for a week and the leakproof lid gives me real peace of mind tossing it in my bag. Switching between the straw and chug opening is intuitive and the whole thing feels solid.

The swap between the straw and chug lid takes about two seconds, which is way more convenient than hauling two separate cups around. Been tossing it in my bag sideways and haven't had a single leak yet.
