Summit 兒童水壺附吸管蓋

My daughter's been using this for a week and her water is still cold at lunchtime — the insulation actually works. The straw lid hasn't leaked once in her lunchbox, which is more than I can say for her last bottle.

Tossed this in my son's backpack for a full day of camp and not a single drop leaked out of the straw lid. The insulated steel really does keep his water cold through the afternoon, which is a win since he refuses anything lukewarm.

My daughter's ice water was still cold after a full day at summer camp, which never happened with her old plastic bottle. The straw lid hasn't leaked a drop in her backpack either.
