زجاجة مياه Summit بغطاء شفاط

My daughter’s water actually stayed cold after a full afternoon at the park, and the straw lid didn’t leak a single drop even when she tossed it in her bag.

I was skeptical about the straw lid staying leak-proof in my toddler's backpack, but after a week of tossing it around, not a single drop leaked. The vacuum insulation kept her water icy cold during a long afternoon at the park, which is a huge win for us.

My daughter’s school water finally survived a full day in the hot car, and the double-walled steel kept it icy cold until after recess. The straw lid clicks shut tight enough that I can toss it in her backpack without a single leak.
