I love my Swift Industries Randonneur bag. It is now called the Peregrine which is awesome (one of my neighbors always calls me that because I had a shirt from Peregrine the metal band. I love the bag and wish I could adapt it to more of my bikes (but front rando racks on some of my bikes wouldn't work without a lot of changing forks which I don't want to do for some of this stuff.

It can fit quite a bit of stuff in it and it has some organizational space. Plus the Nifty Swifties as I call them were nice enough to sew on some patches I had and they did a great job and way better than I could have ever done. It is not a tiny bag but honestly the time I want it smaller are few. For touring it would be excellent especially if you carry fancy cameras not attached to cellular telephones. I do wish to figure out a better way to carry my Boombotix speaker though. I can never get it clipped well on that bag and sometimes don't want it on my stem where I normally mount it.
