If you don't load the duffle too much, you can keep the weight fairly low and this gives enough storage for me for up to a week if I pack light. This also leaves plenty of room for add-ons (like chairs and stuff) strapped on the back. Note the DBz are not waterproof, but I use trash or dry bags and my stuff stays dry.
wolfman makes the bags for dirtbagz
