I am a one bagger too - sort of. I travel with my Red Oxx C-ruck Carry-on Rucksack everywhere. I do carry a camera bag as well but that isn't really "luggage" since it's only a small case for a micro 4/3s Minolta. The Rucksack is awesome and I've been using it for years for my leisure travel. It really doesn't work for business re not good for suits. Red Oxx is my go to bag place as I have Safari Beanos PR6 which can be a one bagger but is probably too big for that (although still a great bag). The Gator is also a great Red Oxx bag but definitely not a one bagger on a cold weather trip that required layers to keep from freezing.
Question: For the bag modders, where/who does the mod? For example, I can think of a couple of things that I'd like to modify on at least one of my Red Oxx bags - where does on get that done? I can't find a good place to hem pants, what are my chances for real work -- are there places that specialize in this stuff?
Cheers
