Summit 兒童水壺附吸管蓋

The straw lid is totally leak-proof even when my son tosses it in his backpack—huge win for parents. Keeps his water ice-cold for hours, and the vacuum insulation means no sweating on the outside. I'm just glad he actually drinks from it now.

My daughter’s water bottle survived a full day at the park and the water was still ice cold when we got home, thanks to that double-walled vacuum insulation. The straw lid hasn’t leaked once in her backpack, which honestly feels like a miracle.

It works fine for keeping water cold, but my kid finds the straw a bit hard to pull up. The insulation is decent for a few hours, not the whole day.
