Is there any "common" material similar/with the same function as Kevlar for civillians?

Hey there! So, i'm a writer for a grounded style superhero/low vigilante story that i'm writing just as an exercise and i've challenged myself to stay totally grounded. Regardless, in a point of the story, the character ends up making his own suit using improvised stuff, mainly fabric.
But, for armor, would there be any equivalent to Kevlar which would make more sense for him to end up getting his hands on? I've searched a lot and all that comes up is really expensive or situational stuff.

PS: The story is set in a fictional city, so there is no second amendment; Firearms and body armor would also be pretty scarce
