FYI, I know that MOW is or was making the Stubby pack. His work is top of the line stuff.
If I do get to the point of mas producing a pack, it will be a budget "kit".
As you will see in future postings, some the components of the pack I don't have official or unofficial dimensions for.
Like most who like to build, finding a low cost and simple way to fabricate a component is an enjoyable challenge. I'm always open to opinion on an easier, better, or lower cost way on making something.
