NBA Summit Waterfles met Rietjesdeksel - 32oz

I’ve been using this bottle for two weeks now and the straw lid really is leak-proof, even when I toss it sideways in my bag. The insulation keeps my water cold through an entire afternoon shift at work.

The double-walled insulation actually holds up—I left it in a hot car for three hours and my water was still ice-cold. The straw lid clicks shut tight enough that I can toss it in my gym bag without a single leak.

I was skeptical about the straw lid staying leak-proof in my gym bag, but after three weeks of tossing it around, not a single drop has escaped. The double-walled insulation keeps my water ice-cold from my morning workout all the way through my afternoon meetings, which is exactly what I needed.
