زجاجة مياه Summit للأطفال بغطاء شفاط

The vacuum insulation actually works—my son’s water stayed ice-cold after hours in the sun at the park. And the straw lid is completely leak-proof even when he tosses it in his backpack.

My daughter's school bag stays dry now thanks to the truly leak-proof straw lid. The vacuum insulation kept her water icy cold for the full six-hour field trip, which is a big win for us.

The straw lid seals tight enough that I tossed it in my son’s backpack with juice and nothing leaked, which is a win. Insulation keeps water cold through a full soccer practice, though I wish the lid were a bit easier for small hands to pop open. Still, it’s sturdy and gets used daily.
