Case for GX1

Hi guys, having just taken delivery of my new Panasonic GX1 with 14-42 PZ and 20mm F1.7, I'm now looking for a small case to keep the camera in with either of the 2 mentioned lenses attached.

What I'm looking for is a pouch type case that I can drop the camera into then drop (not literally) into a backpack that I use everyday. Just worried with the GX1 unprotected that it will get damaged / scratched without some sort of protection.

Any ideas please ?
