Just rationalised mine again actually (so I have room in my pockets for wallet and phone in one pocket, camera in the other). Depending on how bulky my new camera is when it arrives.

One very thin wallet. It's not much more than just two pieces of leather stitched back to back, but has a zipped section for a few coins, card slots etc.

That's it. None of the usual stuff I'd never use.
