Summit Waterfles met Rietjesdeksel

I was skeptical about another kids' bottle, but this one actually holds up—the double-wall insulation keeps water icy through a full afternoon at the park. The straw lid clicks shut with a satisfying snap, and I haven't had a single leak in the backpack yet.

My daughter has spilled about a million other cups in her backpack, but this one has finally ended the flood. The straw lid locks tight when she closes the nozzle and the insulated walls keep her water cold all day at school. It's the only bottle she'll use now.

My son tends to toss his bottle in the backpack, and this straw lid actually stays leak-proof even after a week of school. The vacuum insulation keeps his water cold until lunch, though I wish the straw itself were a bit wider for easier cleaning.
