Summit Vannflaske med sugerørlokk

The straw lid clicks shut with a satisfying snap, and I tested it upside down in my bag with zero leaks. My water stayed ice-cold through an entire afternoon hike. This is exactly what I needed.

This thing actually keeps my water ice cold for hours even when I leave it in my hot car. The straw lid is totally leak-proof too, which is a game-changer for tossing it in my bag without worry.

I was skeptical about vacuum insulation, but my water stayed genuinely cold after a full afternoon in the sun. The straw lid seals tight and hasn’t leaked once in my bag—just wish the mouthpiece was a bit wider for easier cleaning.
