Mana under armor

Through development off the top of my head, I have devised a set of armor that can be easily the best solution to defense for a human in a fight. Mana armor.

Created through chemical re-composition, the total armor unit is made of simply polyester, steel, and mana strings. Lined almost like a pin-striped suit, the entire piece is a single armament, meant to be worn straight on the skin, no garment wear what-so-ever.

How it works

When wearing the attire of the under armor, the suit will feel and react as a normal one piece under armor vest. Through psionic manipulation, the molecules of the polyester and steel are to be combined in a spherical pattern, intertwined with the interlined mana strings. Allowing the polyester and steel into this pattern will inset the steel with the polyester, combining them as a single molecule, allowing the pattern to appear, per molecule, as half polyester, half steel. Once the manipulation has occurred, which should only take second to do so with minimal energy use, the suit will no longer react as a polyester fabric, but as part of the skin itself, taking a much more reflective appearance. With maximum movement, absolutely no irritation, and extreme protection, any human wearing this piece of armament is completely safe from outside penetration under the pressure of about four thousand PSI.
