Nylon, good nylon belts such as Wilderness Tactical have their uses. I don't wear one as a fashion statement, I wear one because it works great in the summer when it'll be covered anyway.
If you ever have the chance to wear a true gun belt, you'll see what all the fuss is about. And they'll do it for years and years. Of course, depending on how heavy your carry is, it may not be as much of a difference.
You know JK the reason I object to the Nylon belt and mall ninja look is because it screams that you are carrying. I have worn a ton. I am just trying to promote the grey man aproach to CC. I also object to the whole vest or, man purse look as it is way too tactical. If I have offended you well get over it.
I wear nylon on my land and at range but not out. As to your assertion that in the summer no one will see. I do not have the luxury of dressing down in the heat.
