Mesa Sport med lockad Chug

The silicone base really does make a difference — I set it down on my desk at 6am and it barely made a sound. It also fits perfectly in my car's cupholder, which my old bottle never did. The lockable lid has survived being tossed in my bag a few times without leaking.

The covered spout is what sold me — no more dust or bugs getting in my drink when I'm outside. The silicone base really does land quietly on my desk, which my coworkers probably appreciate.

Fits perfectly in my car's cupholder, which was the whole reason I bought it, and the covered spout means no drips when it rolls around in the backseat. The lockable lid has held up through a week of daily commutes without a single leak.
