Summit Barnevannflaske med sugerørlokk

Left it in a hot car all afternoon and the water was still cold when my son got to soccer practice. The straw lid hasn't leaked once in his backpack either, which is more than I can say for our old bottle.

Tossed this in my daughter's backpack with ice water before school and it was still cold when she got home six hours later. The straw lid hasn't leaked once, even lying sideways in her bag.

Filled it with ice water before a soccer game and there was still ice rattling around six hours later, which honestly surprised me. The straw lid hasn't leaked once in my son's backpack either, and he's not gentle with his stuff.
