I actually found the side opening variety is super easy to get on.
I set mine on the back of a chair next to the bed. Front of the vest on the back side of the chair.
Left side open.
As I sit up, I grab the left shoulder of the vest with my left hand. Slide my right hand inside along the back of the chair and out the right arm hole.
Lift up and over my head and its on.
Not even out of bed yet and I have every thing I need.
Well except my slippers. dont know where they went.
One interesting thing I have noticed since I became interested in adding body armor to the mix.
You ask a question about it on a prepper site and you will get a 100 positive responses.
You ask that same question on a regular gun forum. The same guys who think nothing about sticking guns in every conceivable location, so as to never be out of reach of a fire arm.
Will call you all kinds of crazy because you feel return fire may be a slight possibility in a home defense situation.
