Mesa Sport med lokket Chug

Tossed this in my bag sideways on the way to the gym and not a single drop leaked, which honestly surprised me. The silicone base is a nice touch too, it lands quiet on my desk instead of that loud clank. Fits my car's cupholder perfectly, no wobbling around while I drive.

The lockable lid with the covered spout is the reason I switched — I can toss this in my bag and not worry about leaks. The silicone base really does land quiet on my desk, no loud clunk.

The silicone base is the detail I didn't know I needed — I set it down on my glass desk every morning and it lands dead silent. The covered spout on the lockable lid means no drips in my bag either, which sold me.
