Summit Barnvattenflaska med sugrörslock

The straw lid really is leak-proof, which is a lifesaver when my daughter throws it in her backpack. It keeps water icy cold even after hours at school.

My son has already dropped his bottle on the concrete twice, and it barely has a scratch. The double-walled insulation kept his water ice-cold during a full afternoon at the park, and the straw lid hasn't leaked once in his backpack.

My daughter left this on the car seat in the sun for a full afternoon and the water was still icy when she got back in. The straw lid hasn't leaked a drop in her backpack, which is a miracle compared to every other bottle we've tried. Worth every penny.
