Gold Flex is a non-woven fabric manufactured by Honeywell from Kevlar, and is often used in ballistic vests and body armor.

Gold Flex is a laminated material consisting of cross-laid, non-woven fibers in a resin matrix.

Honeywell describes "Gold Shield" as being almost identical, only either using two plies instead of four, or using a different resin, depending on version.

Some of these fabrics are only designed with hand-guns in mind basically making anything with a bigger caliber a threat potential.

All layers combined form a larger area of the impact to disperse and keep the bullet from penetrating the carrier.
