Summit Kids Vannflaske med Sugerørlokk

The straw lid is completely leak-proof even when tossed sideways in my son's backpack, which has saved his homework more than once. The double-wall insulation keeps his water cold from morning drop-off until lunchtime.

My daughter kept losing her water bottle caps, but this one's straw lid is totally leak proof so I can toss it in her bag without worry. The vacuum insulation actually keeps her water ice cold all afternoon at the park.

The insulation keeps water cold for a few hours, which is fine for school, but I wish the straw lid was a bit easier for my 5-year-old to open by himself. The stainless steel feels sturdy enough for everyday use.
