Just as Fixies don't look like mainstream bikes, Fixie Touring might not necessarily look like mainstream touring (presently, it does look like maintstream touring with only one gear).
One might take a more lightweight and minimalist approach to Fixie Touring.
What if a rider carried only what would fit comfortably in a Messenger Bag?
Yes, that level of lightweight and compactness costs big bucks, but it represents an alternative way of looking at touring.

As for fenders, I use SKS RaceBlades.
They weigh almost nothing, they pop on and off, and they work, if not perfectly then well enough.
