[quote=“Kevin Granade, post:3, topic:8057”]Boonie hats are in a different category really, just a particular style of hat AFAIK.
Drop pouches and chest rigs though, those tend to have a lot of complicated stitching on very tough materials, and very hard plastic or metal components it might be hard to replicate.[/quote]
I think of the chest rig as an IIFS tactical load bearing vest.

According to this pamphlet it’s made of nylon, foam padding and some plastic for things like buckles. In the cataclysm you could probably use a tough fabric as a substitute for nylon and cloth padding instead of foam. I think that would translate into something like:
15-20 rags
3 plastic chunks
soldering iron
sewing kit with 40 threads
1 tool with sawing quality >= 1 (for making buckles)
