High tech armor vs Ultra-tech armor

Thus while doubling the layers of ballistic cloth might mean DR goes up by about x1.4 times, doubling the thickness of a Ballistic plate roughly doubles its DR.

That said, because layers even hard plates isn't as effective as adding thickness to a single plate, ruling that extra layers add less DR wouldn't be unreasonable. Halving the DR added by the weaker layer (and perhaps quartering that of the 3rd+ layers) would be reasonably simple.

Except that you can only add a layer of flexible armor not hard armor according to rules:

B286: "but you can only layer armor if the inner layer is both flexible and concealable."
