Summit Vannflaske med sugerørlokk

The straw lid is genuinely leak-proof, which is a game-changer for tossing it in a backpack. I also love that the double-wall insulation keeps my son’s juice cold through his whole lunch period.

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.
