In the pantheon of well-dressed gunmen, John Wick is definitely one of the first that comes to mind.
His iconic bespoke bulletproof suits are as much a part of the character as Batman’s cowl or Steve Rogers’ shield. But how feasible would it be to actually work ballistic protection into a normal suit jacket?
There’s a couple elements of this that we need to consider:
If you’re trying to work bullet resistant material into an existing article of clothing, it’s going to have to be soft armor. Something in the range of Level II – Level IIIA.
The material will need to not only be flexible enough to mold to the body during regular movement, but also thin enough that it doesn’t make the suit jacket look like a ski parka. Level II material is approximately 5mm thick, whereas level IIIA is 1.6x thicker at roughly 8mm.
Think about the thickness of the shirt you’re wearing right now. A heavy cotton t-shirt is ~0.4mm thick. So envision layering 12 shirts under a cover garment that needs to be somewhat fitted.
The suit is going to need to look normal, so the facing/presentation fabric is going to have to be a traditional wool or wool blend. The best option is going to be replacing the canvassing of the jacket with ballistic rated material.
Canvass is the interlining that gives the jacket structure and allows it to conform to the body.
The other challenge is, as you can see, when the jacket is buttoned, the centerline from the sternum to the neck is still exposed. Now John Wick seems to address this by adding a waistcoat that pushes the coverage up a little higher and covers the vial organs, but does leave some of the center chest exposed above the nipple line.
The world in which John Wick exists requires some degree of suspension of reality. As such I think it’s fair to assume that this guild of assassins has access to the latest, cutting edge armor technologies that are not available on the open market. Given what’s currently available for purchase, it’s not a far leap to assume there are some restricted nanotechnologies that would offer much more effective ballistic protection in a slimmer, lower profile package.
