In a word, NO!
Modern technology isn't all bad. I firmly believe in using the proper tools for the job. As Cpl P stated, Duluth Packs are for canoeing. For any kind of backpacking you want something that is light and durable. Most backpackers now days use an internal frame pack. I tend to pack heavier loads and use an external frame, but I think the internal is really the smart way to go.
My advice would be to go to an REI, Sportsman's Warehouse, or similar store. Talk to the salesperson and tell them what you have in mind. They will help you pick out the right pack. I also suggest putting some weight in it and carrying it around the store for a while to get a feel for it.
