User blog comment:ACWeapons/How much armor would RWBY characters need?/@comment-24891101-20151211164227/@comment-25396609-20151211193246

I was looking into it awhile back for some reason. I think there was one spider with silk ten times stronger than kevlar, someone was working on genetically modifying goats to produce it in large quantities. I'f I'm not mistaken, ten times the tensile strength would mean 1/10th the thickness, a kevlar vest is a little than an inch thick so one tenth that thickness would be somewhere around the thickness of a thick hoodie, and more flexible than synthetic polymer materials.

I think Remnant would likely have a technology level to produce similar materials, meaning odds are the clothing huntsman and huntresses wear could well be resistant to low caliber bullets, throw in high tech ceramic or alloy hard plates and you get lightweight but sturdy armor easily disguised as civilian clothing.
