I have a Pinnacle to which I'd like to add a frame.
There are lots of local suppliers of plastics and metal (brass or aluminum)so I just need to decide how large to have pieces cut, then I can bend them on my own.
The Pinnacle has a sleeve for it's current foam sheet. The sleeve is smaller than the back of the pack.
Should I limit my new frame to the size of that existing sleeve, or should I make the framesheet to fit the entire width of the pack?
