メサスポーツ チャグ付きカバー

Tossed this in my bag for a hike and not a single drop leaked, even with the spout cover flipped down. It actually fits my car's cupholder too, which my last bottle never did.

The silicone base is the sleeper feature here — I set it down on my glass desk every morning and it makes zero clink. Lid locks shut too, so I've tossed it in my bag sideways without a single leak.

Fits perfectly in my car's cupholder, which was the whole reason I bought a 30oz in the first place. The covered spout is a nice touch too, no dust or bugs getting in while it sits on my desk.
