サミット キッズ ストロー蓋付きウォーターボトル

My daughter left this in the car on a 90-degree afternoon, and the water was still ice-cold hours later thanks to the double-walled insulation. The straw nozzle flips shut easily, and not a single drop leaked when she tossed it in her backpack.

I was worried the straw lid might leak in my son's backpack, but it's been totally leak-proof so far. Love that the double-walled insulation keeps his water cold even after hours at the park.

My daughter's been using this bottle for a week and the vacuum insulation actually keeps her water ice-cold through a full day at school. The leak-proof straw lid is a lifesaver—no spills in her backpack, even when she tosses it in sideways.
