It's a plastic lid with some kind of cap on the bottom. I'm not sure if it's supposed to be removable but the cap came off of mine and revealed some weird styrofoam inside. Water gets inside this cavity inside the lid as well as around the gaskets/threading and it begins to smell very quickly.
Hi Dillion, we're so sorry to hear about the state of your MiiR® Fitz Etch 23-oz Bottle. It sounds like this is definitely a quality control issue and we'd be happy to help out with a return or exchange. You can begin either process here, https://www.patagonia.ca/canada-returns.html.

Very Cool Design
The bottle looks and feels really great, Ive gotten a lot of compliments on the bottle. Also keeps my water really cold for a long time. It is definitely worth buying!

Bottle keeps cold water cold. It is heavy and feels substantial when you hold it. It fell out of my bag onto some cement and the paint barely even chipped, the cement was obliterated. I now owe the parking lot $2,000.00 to repair the crater left by this bottle.
