I'm not explaining myself well, maybe an example.
Wrap a plastic bag around your waist, then hang a hunting knife from it. The bag sags because it has nothing in it to support its' shape. In the same way, the belt on the G4 collapses because there is nothing, other than socks, to give it form. Maybe with foam instead of socks, it would not sag, not sure.
The problem I had was that the belt sagged (collapsed?) because there was nothing to hold it in the shape of a belt. As someone said, even paracord would make a belt, but it would be uncomfortable. Same here.
Is that better?
Life should not be a journey to the grave with the intent of arriving safely in a well preserved body, but to skid in broadside, thoroughly used up, worn out, and loudly proclaiming Wow! What a Ride!
