I think that is our problem, we have a hard time imagining how the energy could be distributed across the garment.
You could sell me on Non-Newtonian-Kevlar though: Pliant to a slow crease, rock-hard with a sudden strike.

Oh man I thought I was making that up, but it's a thing! https://en.wikipedia.org/wiki/Liquid_Armor https://en.wikipedia.org/wiki/Liquid_Armor The future is now!

If we are talking about the force of a punch from a good boxer, we only have to spread it over the area of the front of a boxing glove. That seems perfectly reasonable for a fabric layer soaked with a non-Newtonian fluid.

All readily available online, if you can afford something like $200 per 2ml of silica nanoparticles. It would be amazing to see one of the YouTube channels that has tried making their own, just make the real thing. I imagine a suit made of dripping wet Kevlar wouldn't be too comfortable though. John Wick would experience some chafing.
