Summit Kids Vandflaske med sugerør

My daughter left this in the car on a 90-degree day, and the water was still icy four hours later thanks to that double-walled insulation. The straw lid clicks shut tight enough that she can toss it in her backpack without a single leak.

My daughter's been using this at school for a week and the vacuum insulation actually keeps her water ice-cold until afternoon. The leak-proof straw lid is a huge win—no more wet lunchboxes.

I like that this bottle actually keeps water cold through a full school day, even when left in a warm classroom. The straw lid works smoothly and hasn't leaked in my kid's backpack so far.
