The concept of the gray man is to blend in. This person can disappear into the crowd and never be noticed.
For all points and purposes, shouldn’t preppers / survivalist be practicing gray man on an everyday basis? As stated in another post, tacticool has no place in prepping. At all times we should blend in. Sometimes we need to be reminded on some of the simple things.
Some of the ways I practice “gray man”.
Pants. In rural areas such as where I live pants are levis, wranglers or some kind of blue jean. Cities and suburbs maybe khakis or slacks.
I stay away from “tactical” looking cargo pants. Keep it simple and basic. I do not own a pair of slacks. Rarely, and I mean “rarely” will I wear khakis.
