Mesa Sport med lockad Chug

The spout cover being lockable is a game changer for me—I tossed it in my work bag with no leaks at all. The silicone base also makes setting it down on my desk quietly, which my coworkers probably appreciate more than I do.

Finally a bottle that actually fits my car's cupholder without wobbling, and the silicone base means it doesn't clatter on my desk every time I set it down. The lockable lid stays shut in my bag, though I do have to remember to flip the spout cover open before drinking.

The lockable lid with the covered spout was the reason I grabbed this, and it hasn't leaked a drop in my bag all week. It's nice that the 24oz size slides right into my car's cupholder without wobbling.
