Summit Barnevannflaske med sugerørlokk

My kid left this in the car on a 90-degree day, and the water was still icy when we got back hours later — the vacuum insulation really holds up. The straw lid clicks closed tight enough that I tossed it in her backpack with zero leaks, which is a win for me.

The straw lid snaps shut with a satisfying click, and I’ve tossed it in my bag sideways without a single drop leaking. Ice water still has ice cubes after a full school day, which is honestly better than my own bottle manages.

My daughter’s been using this for a week and I’m impressed the water stays cold for hours, even after school. The straw lid is completely leak-proof, so no mess in her backpack.
