Summit Kids 水筒 ストロー蓋付き

The double-walled insulation actually works—ice cubes were still solid after a full afternoon at the park, which is more than I can say for past bottles. The straw lid is easy for my daughter to flip open with one hand, and I haven’t seen a single drop leak from her backpack since we got it.

My son loves that the straw lid doesn't leak even when he tosses this bottle into his backpack sideways. The double-wall insulation kept his water cool during the whole soccer practice.

My daughter’s water stayed ice-cold after a full day at the park, and the double-walled insulation really impressed me. The straw lid clicks shut securely, so I don’t worry about leaks in her backpack.
