Summit Kids Vattenflaska med sugrörslock

The double-wall insulation is incredible—I put ice in it at 7am and it was still frozen when my daughter came home from school. The straw lid seals tightly enough that she can toss it in her backpack without any leaks.

My son loves that his water stays ice-cold even after hours at the playground, but the straw lid can be a bit tough for him to pop up on his own. Still, it's totally leak-proof in his lunchbox, which is the main thing.

The straw lid works as advertised for no spills, but my kid has trouble getting the last sip of water out. The insulation keeps drinks cold for hours, which is nice, but the bottle feels a bit bulky for small hands to carry.
