You might want to focus on load-bearing and look at mil-surp. I picked this up and it remains a work in progress. The digicam is the IFAC, and I scrounged Israeli bandages, chest seal bandages, and some recommended EMT items. The suspenders are very comfortable but I had to buy the padded shoulder pads from the seller. The belt is generous and easy to adjust. The outside of the padded belt is wall-to-wall molle. There's lots of mil-surp still on eBay.
