Summit 吸管蓋水瓶

Kept my iced coffee ice-cold through a full afternoon of errands, and the straw lid actually stays sealed in my bag even when the nozzle's closed. The vacuum insulation really does the job, no condensation on the outside either.

I’ve had this bottle for a few weeks and the vacuum insulation really keeps water icy even after hours outside. The only small thing is the straw lid can be a bit stiff to open at first, but it does seal perfectly when closed.

The straw lid seals tight when flipped shut, so no leaks in my bag, which is a relief. But the vacuum insulation only keeps things cold for a few hours, not the whole day I was hoping for, so I'm lukewarm on it.
