Summit 兒童水壺附吸管蓋

My son’s water actually stayed cold during a full afternoon at the park, which is impressive for a kids’ bottle. The straw lid is truly leak-proof, so no mess in his backpack.

My daughter’s been using this for a week and the straw lid hasn’t leaked once in her backpack, which is a huge win. The vacuum insulation really does keep her water cold through lunch.

The double-walled insulation actually keeps ice cubes solid for a good six hours in my daughter's backpack. Her drink is still cold at lunchtime, and the straw lid hasn't leaked once yet.
