Summit Kinderwaterfles met Rietjesdeksel

I love that the straw lid is truly leak-proof — my son accidentally left it sideways in his backpack and not a drop spilled. The vacuum insulation keeps his water cold even after hours outside, which is a huge win for school days. It’s held up to his rough handling way better than I expected.

My daughter drops this thing constantly and the straw lid has never once leaked in her backpack, which is a small miracle. The double-walled steel keeps her water icy from morning drop-off all the way to after-school soccer. Worth every penny.

The vacuum insulation works perfectly — my daughter's water stayed icy cold after a full afternoon at the park. The straw lid is completely leak-proof, even when she tosses it in her backpack.
