Flexible plastic stiffener for pack?

[AndyD]

Does anyone know if these can be bought anywhere?
Ideally though, would like to make my own, just struggling to think where I can get plastic that's suitable!

Cheers,
Andy

Use a sitmat?

Old 20l Karrimor has something similar in it, and does the trick.

Are you wanting to hold a comfortable shape? You could try sandwiching some flat aluminium bar bewtween closed cell foam.
Is it like the F-format system used in the karrimor Sabre sf you are wanting?

There's already a foam pad inside the pouch at the back of the pack,as I understand, the pack when new also has a flexible plastic stiffener to add rigidity and to stop items pushing through into the wearers back,this is what I'm after.

If it helps it's a Spec-Ops 3 day assault pack.

The old German Army packs actually use their closed cell kip mats for this. That's an option.
One thing I find very useful in the field is a cutting board. This one is a really useful size for your purpose.

I usually stow this down the front of my pack to solve abrasion risk and unsightly bulges. Fits well in my 35L and 45L packs.

I use a chopping board in my modified m39 (no frame) and it works well but cane make it a bit sweaty in really hot weather

I have a Sabre 45 without a stiffener. What size mat would fit?

Use a sitmat?

What sort of thickness, height depth etc, are you looking for a full back piece a small rod a few strips? I found the old fiberglass poles are exelent stiffening rods as it's hard to put short ones under any real tension, better than aluminium for this task by far !
