Summit Kids Drinkfles met Rietjesdeksel

I’ve tested a lot of bottles that claim to be leak-proof, but this one actually holds up in my bag even after my kid throws it around. The straw nozzle stays shut tight, and the vacuum insulation keeps the water ice-cold through a full afternoon at the park. It’s the first one I haven’t had to wipe

My youngest is notorious for leaving her bottle in a hot car, but this one still had ice cubes hours later. The leak-proof straw lid has survived being tossed in her school bag without a single spill.

The vacuum insulation keeps the water cold for a few hours, which is nice for school. But the straw lid, while advertised as leak-proof, still dribbles a little if it tips over in a lunch bag. It's fine for the price, just not as sturdy as I hoped.
