Summit キッズ ストローフタ付きウォーターボトル

We’re three days into a road trip and the water’s still ice-cold this afternoon, which is exactly what I hoped for with the double-walled insulation. The straw lid clicks shut tight enough that my daughter can toss it in her backpack without any leaks.

My son’s straw lid has survived being tossed in the car seat and dropped on pavement without a single leak, which is a miracle. The vacuum insulation actually keeps his water cold through a full afternoon at soccer practice, not just the first hour.

My daughter's drink stays ice-cold even after hours at the park thanks to the double-walled insulation. The straw lid hasn't leaked once in her backpack, which is a huge relief for me.
