NFL Summit Geïsoleerde Waterfles met Rietjesdeksel

The vacuum insulation actually works—my ice water still had ice cubes after a three-hour hike in the sun. The straw lid seals tight enough to toss in my gym bag without any leaks, too.

I’ve been using this for my morning commute, and the double-walled insulation really holds up—ice is still clinking around after a full workday. The straw lid snaps shut tight enough that I can toss it in my bag without worrying about leaks.

Finally a bottle that actually keeps my water ice-cold through an entire afternoon at the stadium, even in direct sun. The vacuum insulation is no joke—I had ice cubes still floating after four hours. And the straw lid seals tight enough that I can toss it in my bag without a drop leaking.
