He does a pretty nice video demo...

Of course, I would like to see him try to fill one of those and carry it around a bit. I think it would rate a less enthusiastic thumb then.

When I got my fatboy I was pretty excited that it would work, carried it, rearranged it, carried it, left it home in the closet. Then the jumbo came out and I thought great, finally the right size and much better configuration. Well is was, but after many attempts it too resides mostly in the closet.

The old Filson bag is vastly better for my daily carry as it does not restrict my options to essentially nothing.
