You have probably heard of "ballistic" nylon, but everyone knows that soft armor is made of Kevlar, right? Well, it is today (and other similar fibers). But a few decades back, before Kevlar had been invented, Smith & Wesson was selling soft body armor made using layers of nylon - "ballistic" nylon.
Thanks to Movie Gun Services, I had a chance to take a look at a vintage set of S&W body armor, complete with steel plates (rated for .38 S&W in the soft panels and .30 Carbine on the plates). For good measure, I also pulled out some revolver-launched tear gas grenades from the same period. Enjoy!
