During the late 1920s through the early 1930s, gunmen from criminal gangs in the United States began wearing less-expensive vests made from thick layers of cotton padding and cloth. These early vests could absorb the impact of handgun rounds such as [[.22 Long Rifle]], [[.25 ACP]], [[.32 S&W Long]], [[.32 S&W]], [[.380 ACP]], [[.38 Special]] and [[.45 ACP]] traveling at speeds of up to {{convert|300|m/s|abbr=on}}.<ref>{{cite web | url=https://patents.google.com/patent/US2052684A/en | title=Armor }}</ref> To overcome these vests, law enforcement agents began using the newer and more powerful [[.38 Super]], and later the [[.357 Magnum]] cartridge.{{Citation needed|date=November 2019}}

Meanwhile, the Dunrite Bulletproof Vest, produced by Detective Publishing Company Chicago, was used by some members of law enforcement. The vest itself was made of wool, but it's protection came from 15 pounds of metal.

Vests of that sort were often stolen or obtained in other ways by gangsters (Such as originals or copies being sold directly to them in secret). One Dunrite Bullet Bullerproof Vest was found in the back of Bonnie and Clyde’s car.<ref name=":0" />
