Summit 水瓶附吸管蓋

The straw lid seals completely tight in my bag, no drips, and the double-wall keeps ice water cold well past lunch. The vacuum insulation works exactly as promised.

I've taken this bottle on every outing since it arrived, and the vacuum insulation actually delivers—ice cubes survived a full afternoon in the car. The straw lid clicks shut tight and I've thrown it sideways in my bag without a single leak.

Cold water stayed icy through my entire afternoon hike, which is exactly what I needed from a bottle like this. The straw lid is convenient, though I do wish the mouthpiece had a bit more give when you sip.
