Summit 兒童吸管蓋水瓶

The vacuum insulation really works—my daughter’s water stayed cold after a full afternoon at the park. The straw lid is easy for her to open by herself and hasn’t leaked once in her backpack.

My kid drops this thing constantly and the straw lid still hasn't leaked a single drop into her backpack. The double-wall insulation actually keeps her water icy cold through a full soccer practice, even in the sun.

Left it in the car on a hot afternoon and the water was still ice-cold when we got back—the double-walled insulation really does its job. The straw lid seals tight enough that my toddler can toss it in their backpack without a single leak.
