ROCK SOLID - EZ Top - Small

The one-handed flip top actually works, even in the dark when I'm half asleep. Seals tight too, no leaks rolling around in my bag.

Wasn't sure a cap could make that much difference, but the leak-proof seal actually holds up when it gets knocked over on my nightstand. Being able to open it with one hand without fumbling is the part I didn't know I needed.

The one-handed flip is genuinely effortless, even in the dark at 3 a.m. I’ve knocked it over twice already and not a drop spilled, so it’s doing exactly what it promises.
