Cool bag, mustachiod.

eddubal, those bags do look nice. But, as you guessed, it's not quite what I'm looking for--the semi-rigid shape of the bags makes them a bit too 'this-is-a-saddle-bag-and-nothing-else' for my taste (if that makes sense). But the way they're attached to the saddle (across the back, rather than the Burrito Bag's way) provided some food for thought.
