サミットキッズ水筒ストロー蓋付き

My daughter’s been using this for a week and I’m genuinely impressed the vacuum insulation keeps her water icy cold even after hours in the sun. The double-walled stainless steel feels sturdy enough to survive drops from the playground.

My daughter’s been using this every day for a week, and the double-walled insulation really keeps her water ice-cold during school. The straw lid hasn’t leaked once in her backpack, which is a huge win.

The straw lid really is leak-proof, even when my son tosses it sideways in his backpack. It keeps water cold through his whole school day, which is great. Only wish it came in a slightly bigger size for older kids.
