Summit Børnevandflaske med sugerørslåg

The vacuum insulation actually holds up — ice cubes are still clinking around at lunchtime when I pack it in the morning. Straw lid’s easy enough for my four-year-old to flip up herself, and not a drop leaked in her backpack all week. That’s the win I needed.

My daughter’s been using this for a week and it really keeps her water cold during school—the vacuum insulation works great. The straw lid is totally leak-proof in her backpack, which is a huge relief.

The straw lid seals properly even when my toddler throws it in the bag sideways, and the double-wall keeps water chilly for a full school day. Only slight gripe is the lid takes a bit of effort to pop open for small hands, but it's a solid buy overall.
