Summit キッズ水筒 ストロー付き

My kid’s a total grazer, so the straw lid being leak-proof is a huge win—I can toss this in his backpack without worrying about a soaked homework folder. The vacuum insulation actually keeps water icy cold even after a full morning at the playground, which is exactly what I hoped for.

Finally a bottle that actually keeps my kid's water cold through a whole soccer practice, even in the summer heat. The straw lid hasn't leaked once in the three weeks we've been tossing it in the backpack, and it's survived a few drops on the pavement.

The double-walled insulation does its job—ice cubes are still clinking around after a few hours in the car. My only gripe is the straw lid takes a firm twist to seal, so my kid sometimes leaves it half-closed and we get a tiny drip, but it’s not a real leak.
