A ballistic vest carrier cover has a mantle that goes over the wearer's shoulders from the front waist to rear waist. It has a fabric outer layer, an interlining heat-fused to the back of the outer layer, and a liner. The cover is designed to fit over a pullover shirt so the combination appears as a standard uniform shirt. The liner attaches to the outer layer at the front and rear waist, neck, and along the sides from front armor openings to rear armor openings, thereby producing front and rear pockets for receiving the body armor panel carriers through the armor openings. The front of the mantle attaches to the rear at the waist by zippers. One zipper component is on a stretch panel that extends from the outer layer at the rear armor opening and the other zipper component is on the outer layer at the front armor opening.

It has been found that basalt particles, when combined with a resin binder and a reinforcing material, such as fiberglass, provide unexpected strength, fire-resistance, radiation impermeability, and projectile shielding for ballistic armor / shields, fire-resistant building panels, construction blocks and protective coatings on substrates. The armor panels can be worn, as in a bullet-proof vest, or can be used as a shield to protect a vehicle, aircraft or other structures as projectile penetration-resistant and fire and radiation resistant materials.
