I'm in the process of cutting out and preparing to sew a pack very similar to Duluth's #4 Original 72 liter pack. Although I have a fair bit of 9-10 oz leather on hand this first one will get nylon or polyester webbing closure straps and buckles for the flap and tumpline end straps and a modern pack suspension set for the shoulder straps.
The suspension straps will attach to a ladder of 3/4" straps on the pack allowing it to be adjusted vertically on the bag; higher on the bag for carrying a canoe and maybe lower when not carrying a canoe so the pack rides more like a standard backpack. That feature isn't strictly necessary but as the harness is designed for it a few more 4" long strips of webbing won't add more than a fraction of an ounce of weight anyway. And as this is my first portage pack it means I can't stitch and rivet a harness on at the wrong height.
Besides, as I have a lot of #8/18 oz canvas on hand it won't be a featherweight pack by any means. For comparison, Duluth uses 15 oz canvas so in canvas alone it will be several ounces heavier than the Duluth #4......
Now I have another thought and so I'm wondering what folks might think about a roll top closure a' la a dry bag instead of the traditional flap. A roll top would be more secure, keep more crud and rain out and act as a compression strap set. The only downside I see would be that it would be more awkward to have something like an axe haft stick out of the pack and maybe a bit slower to dig something out during the day.
At any rate, the pack I'm working on now is already getting cut out so a roll top would be for a later pack if at all.
Please, let me know you thoughts. And thanks in advance.
