Summit キッズ水筒 ストロー付き

My daughter’s water stayed icy cold after a full afternoon at the park, and the double-walled insulation really impressed me. The straw lid hasn’t leaked once in her backpack, which is a huge relief.

The straw lid really is leak-proof, which is a lifesaver for the lunchbox. And I love that it's double-walled because the outside never sweats, even after hours in the car.

My daughter’s drinks stay cold even after hours at school, and the straw lid hasn’t leaked once in her backpack. It’s a solid upgrade from her old plastic bottle.
