I regularly utilize a Coaxsher chest pack for SAR, and sometimes for recreational use (front-country and backcountry skiing, mountaineering, peak-bagging, etc.) and I wanted to give a walk-through of what I carry in it. Perhaps you’ll find some of these ideas useful for your use, whatever that
@Ham Radio Crash Course recently did a video review (https://www.youtube.com/watch?v=EILFg0RPyOY) comparing the Coaxsher RCP-1 chest harness to a similar Abree model. I primarily use the slightly smaller Coaxsher RP-1 Scout (https://amzn.to/2Ojyukl) which is a bit smaller and more comfortable to wear. It still carries everything I need.
