leather is no longer a performance fabric? what?
Some bikepackers' riding backpacks approach that of Michael Palin's on his 'flying circus' bike tour posted by massive D.
my goal is to pack UL enough with a rackless setup to not need a backpack.
I do carry one of those cheap, promotional musette bags for extra carrying capacity of food and what not. not the best for the middle of the woods so maybe a cheap collapsible backpack like some riders are carrying might be in order.
one tip i haven't seen mentioned yet (staeph1 might have but i don't think so) is padding the rack if you use a rack.
Pad the rack with strips of foam or poly tubing (taping sections of old foam sleeping pad to your rack) to cut down on abrasion of lightweight bags being strapped to it.
