ROCK SOLID - EZ Top - Medium

I was skeptical about the "leak-proof" claim, but after tossing it in my gym bag sideways for a week, not a single drop escaped. The one-handed twist is smooth and feels solid in the dark, which is exactly what I needed for those 2 a.m. moments.

The one-handed cap is a game-changer at 2 a.m. — I can pop it off without fumbling or spilling a drop, and it’s sealed tight enough that I’ve tipped it over in my bag twice with zero leaks. Exactly what my nightstand needed.
