Summit 兒童水瓶，附吸管蓋

My daughter left this in the car on a hot afternoon and the water was still ice cold hours later, the vacuum insulation really delivers. She loves the straw lid, and it clicks shut securely enough that I don't worry about spills in her backpack.

The straw lid is completely leak-proof, which is a game-changer for stuffing it into a backpack. My son can have it sideways and not a drop comes out, plus the insulated metal keeps his water cold for hours at school.

My daughter’s water stayed icy cold after a full afternoon at the park, and I love that the straw lid is truly leak-proof when closed. The double-walled insulation is a game-changer for school lunches.
