Butelka Summit Kids ze słomką i pokrywką

My son left this on the counter overnight and the ice cubes were still intact the next morning, so the double-walled insulation is the real deal. The straw lid clicks shut firmly and I’ve tossed it in his backpack with no leaks, which is all I ask for.

Even after sitting in the car all afternoon, the water is still ice-cold—the double-walled insulation really does its job. And the straw lid hasn’t leaked once in the two weeks we’ve been using it, even when my son tosses it in his backpack.

My daughter loves that her water stays ice-cold even after hours at the playground. The straw lid is truly leak-proof, which is a lifesaver for her backpack. I just wish the lid were a bit easier for her small hands to open on the first try.
