Rally 蛋白質搖搖杯

I've been using this shaker for my morning iced coffee and the double wall insulation actually keeps it cold for hours without any condensation on the outside. The pop-up spout makes drinking really easy even while driving.

The twist-on lid with the handle loop makes it super easy to carry to the gym, and the spout pops open smoothly for sipping mid-workout. My drink stayed cold for a solid two hours during a long hike, which was a pleasant surprise for a plastic shaker.

I was skeptical about the double-wall insulation, but it kept my iced coffee ice-cold through a two-hour meeting. The twist-on lid feels solid and the spout pops open smoothly for easy drinking.
