Leica & DSLR?? How do you store both on TRAVEL?

Hello guys, I plan on going to Europe in the next year and I want to take along my 5D Mark 2 and my Leica M8... maybe 2-3 lenses at the very most.

What bags have worked for you guys? I pref something that looks more subtle and doesn't scream "THIS IS A CAMERA bag!"

Thanks
