Summit 兒童吸管蓋水瓶

The straw lid seals so well that I tossed it in the bottom of my bag without a second thought, and not a single drop leaked. Ice water from the morning was still cold after a full afternoon at the playground, which surprised me given how much she tips it around.

My daughter's been using this for a week, and the vacuum insulation actually keeps her water ice-cold even after hours at the playground. The straw lid is leak-proof so far, which is a huge relief for her backpack.

It keeps drinks cold for hours, which is great for school, but the straw lid is a bit stiff for my six-year-old to pop up on her own. She manages, just takes a few tries each time.
