Summit Vannflaske med sugerørlokk

My kid left this in the car on a hot afternoon and the water was still ice-cold hours later. The straw lid locks securely when the nozzle's flipped shut, so no mess in the lunchbox either. Honestly, this is the only bottle we've used without leaks since we switched.

The double-walled insulation keeps the water cold for hours, which is perfect for school lunches. My only small issue is that the straw takes a bit of effort for little hands to pop up.

The straw lid really is leak-proof in the closed position, which saves me from wiping up juice spills in the lunchbox. It keeps water cold for the whole school day, though I wish the lid had a carrying loop.
