サミット キッズ ストロー蓋付きウォーターボトル

My son's drink stayed ice-cold during a full soccer practice thanks to the double-walled insulation, and the straw lid didn't leak a single drop when tossed in his bag.

The double-wall insulation is incredible—I put ice in it at 7am and it was still frozen when my daughter came home from school. The straw lid seals tightly enough that she can toss it in her backpack without any leaks.

My son loves that his water stays ice-cold even after hours at the playground, but the straw lid can be a bit tough for him to pop up on his own. Still, it's totally leak-proof in his lunchbox, which is the main thing.
