The Why is the most valuable input. As to why I don't layer my gear more. I do, I just tend not to have a lot on me because I don't have a lot of real estate. I carry the basics and then some. My whole approach is to look at situations and posture accordingly. My whole train of thought is to go to a certain posture level based on the threat. Since this is geared towards me being home, that's how my gear is set up.
