The other night I had a wild hair to make a pack similar to some of the more basic Duluth Packs. a yard or so of duck cloth, some leather and a few buckles later and I have this. After making it I can say it is worth the $85 for Duluth's version. This was a pain in the rear to make, but I made it all by hand with hand stitching. The duck cloth is coated with beeswax. It's not my best work. I kinda threw it together on a whim. I got dye on the fabric, straps are crooked, but it works.
It will hold enough stuff for a day trip or a light hike. This design is not comfortable with a lot of weight.
God Bless Yall!
