Summit Børne Vandflaske med Sugerørslåg

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.

The straw lid is indeed leakproof which is great for the school bag, but the nozzle feels a bit stiff for my 6-year-old to open easily on their own. Keeps drinks cold for a few hours though, which works for lunch.
