Butelka Summit dla dzieci z nakrętką ze słomką

We've had this for two weeks and it's already survived the school bag toss test, plus the straw lid truly doesn't leak when my daughter shakes it upside down. The double-walled steel keeps her water icy from morning drop-off to afternoon pickup, which is a win on hot days.

First trip to the beach last weekend and the ice cubes were still clinking around after five hours in the sun, that double-wall insulation really earns its keep. The straw lid snapped shut without a single drip even after my son tossed it in the sand.

My daughter’s been using this for a week and the vacuum insulation really does keep her water ice-cold even after hours at school. The leak-proof straw lid is a lifesaver in her backpack—no spills yet.
