Summit barnvattenflaska med sugrörslock

The straw lid really is leak-proof—my daughter tossed it in her backpack with loose papers and nothing got wet. The vacuum insulation kept her water ice cold after a full day at camp. Worth it for the peace of mind alone.

My kids have been using these for school lunches, and the vacuum insulation actually keeps their water cold even after hours in a hot classroom. The leak-proof straw lid is a lifesaver for my toddler’s backpack.

My kid’s water has stayed ice-cold through a full day of school, even in the car on the way home. The straw lid really is leak-proof, so I can toss it in the backpack without worrying about soaked homework. Worth every penny.
