I have a Eberlestock Bandit backpack. I am wondering if anyone has done a DIY mod for any pack to add a little structure to the main compartment. Somthing simple but effective to keep the pack from falling in on itself. Thanks!
Thanks for the info! I’ll be looking into itThe two materials I’ve used:
HDPE plastic sheets
Corrugated plastic used for signs. Cheapest way is to wait for an election and get a sign.

This will give you a basic idea:

They add carbon fiber arrow stays (supports) to increase rigidity.
You can also add aluminum stays to stiffen it further:

Sewing a stave sleeve is probably best, but gluing a sleeve on with epoxy or something might be a viable hack, or even bolting it on.
I have one pack that uses a plain HPDE sheet in a sleeve (the size of the front of the pack, that sits against my back). It isn't very structural but it is light and it helps the bag maintain it's shape.
