サミット キッズ ストローリッド水筒

My daughter left this in the car on a 90-degree day, and the water was still icy-cold four hours later when we got back. The double-wall insulation really holds up, and the straw lid hasn’t leaked a single drop in her backpack all week.

The straw lid clicks shut tight enough that I don’t worry about it leaking in the school bag, which is huge for us. Even after a full morning outside, the water still feels fridge-cold thanks to that double-walled build.

My daughter’s drink stayed icy cold after a whole morning at the park, and the straw lid didn’t leak a single drop in her backpack. That vacuum insulation is a lifesaver for busy days.
