Summit 水瓶附吸管蓋

Easy to sip from the straw lid without worrying about spills, and the vacuum insulation really works—my water stayed icy cold during a long hike. I like that the close mechanism is simple and actually leak-proof when I toss it in my bag.

The straw lid actually seals tight enough that I tossed it in my bag sideways without a drop escaping, which is a huge win for me. I also love that the double-walled insulation keeps my water icy cold for hours even in a hot car, so it’s become my daily driver.

Ice stays cold through my whole afternoon shift, which is exactly what I needed from the double-walled insulation. Only gripe is the straw takes a little extra suction at first, but once you get going it flows fine.
