The Quencher H2.O FlowState™ 隨行杯蓋 | 40 OZ

The FlowState lid snaps on without any fuss, and I've tossed the tumbler in my bag sideways with zero leaks. My iced coffee stayed cold for hours, which is exactly what I needed for long workdays.

This lid seals tight enough that I can toss my tumbler in my bag sideways without a drop escaping, which is exactly what I needed. The rotating cap is smooth and clicks into place easily, and it fits my existing cup perfectly.

I was a little worried a replacement lid wouldn't fit right, but this one snaps on perfectly and the rotating spout is super handy for sipping hot coffee without burning my mouth. The insulation lock still keeps my ice water cold all day long.
