Impact Gel is a Promethean Technology produced by Sky Industries that allows a metamaterial with the consistancy of jello to absorb direct force and divert it away from a single point. It is very effective, but very expensive.

A flak jacket with an Impact Gel layer can be hit point blank with a medium caliber round and the wearer would barely feel it.

It is used in military vehicles, portective gear, sports equipment, and the SCU's body armor uses a layer.
