Summit Waterfles met Rietjesdeksel

I was skeptical about the straw lid staying leak-proof in a backpack, but after three weeks of tossing it around, not a single drop has escaped. The vacuum insulation keeps water ice-cold through an entire afternoon at the park, which is exactly what we needed.

My kid takes this to school every day and the vacuum insulation actually works — ice cubes are still there after lunch. The straw lid clicks shut tight so there's never juice all over the backpack, which is a total win for me.

My kid's drinks stay ice-cold for hours during school, which is exactly what I needed. The straw lid seals tight enough that I'm not worried about leaks in their backpack, though the nozzle takes a bit of effort to flip open.
