Overall, I carry a water filter, lighter, lighter fluid, hand sanitizer, solar charger for iPhone, and other items as seen in the photo.
My iPhone is GPS capable without a WiFi or cellular connection. It is loaded with offline GAIA maps for 100miles from my house. I is the Spyglass app for a compass and line of sight orienteering. On my hiking pole is a fluid based compass and thermometer. I would attach my pistol to the belt when in use.
