I found these in some of my FIL's things. They appear to be made from cotton duck or canvas-type material. Does anyone who has been around saws and chaps longer than I know what type of material is sandwiched between the cotton? Would it be kevlar type, long, stringy fibers like we see today in chaps? These would probably be from the 70's-80's era. No nylon in these! Thanks fellas......here are the pics.
