Took this on a weekend hike and the leakproof lid lived up to its name—tossed it in my bag upside down and not a drop spilled. The 20oz size fits perfectly in my car cup holder too, which is a bonus I didn't expect.

The flip straw lid is the real deal—I tossed it in my bag sideways and not a drop leaked, which is exactly what I needed for my commute. Twenty ounces feels just right for a solid day of sipping without the bulk of a bigger bottle.

Carried it around all day with the flip straw closed in my bag and not a single drop leaked, which honestly surprised me. The 20 oz size fits perfectly in my car cup holder, and the straw flips open one-handed when I'm driving. This is my new everyday go-to.
