Summit 吸管蓋水瓶

I can toss this in my bag without worrying about spills, and the double-wall insulation keeps my water ice-cold through a whole afternoon hike.

Really glad the straw lid is leak-proof — tossed it in my work bag without a second thought and nothing spilled. The double-wall insulation keeps my water cold through back-to-back meetings, which was exactly what I needed.

Keeps my water icy for hours even in the car, and the straw lid seals tight enough to toss in my bag without worrying. Just wish the nozzle were a bit easier to pop open one-handed, but that's a small thing.
