Disney Summit 水瓶（附吸管蓋）

I took this to the beach and my water stayed ice-cold for nearly six hours, even in direct sun. The leak-proof straw lid is a lifesaver when it gets knocked over in my bag.

The straw lid mechanism clicks securely shut, and I love that the nozzle stays leak-proof even when I toss it in my gym bag. The vacuum insulation really works—ice cubes were still clinking around after a full morning at the park.

Left it in a hot car all afternoon and the water was still cold that evening — the double-wall insulation genuinely works. The straw lid hasn't leaked once in my backpack, even with the nozzle closed and the bottle tipped sideways.
