The key factor is the attire of other individuals in the vicinity. If you carry a backpack, regardless of whether it appears as a non-military design, and none of the other people in the area are carrying one, then it will attract attention. I wouldn't even want to hint that I'm a prepper.

OK, since I donīt know your surroundings itīs hard to comment anything. Here in my country we donīt have that kind of problem. Backpacks are a commong thing to lug your daily stuff and prepping is not a thing here.
