I reinforced my jeans with kevlar even added pockets for knee and hip padding. Very fancy! but now I have all this extra kevlar and cordura hanging around. If anyone is interested we can come up with a price and you can send me pants to have reinforced with optional padding.
the kevlar is 1080 denier the cordura is 1000 denier, if you want to go fancy i can even add a mesh soft lining on top of the kevlar/cordura
