Many loggers don't wear all the safety gear they should and chaps are often not used.

I would probably repair them. The way they work is the fill material clogs the chain loop and stops it. I'd be looking for a replacement material to put in there and cover with a patch to restore the original performance.

No flames from me. I'm the bozo with a new set of unworn chaps (but I promise I will be wearing them from now on after cutting two slices across my jeans leg.) Just lucky I didn't really get a bad injury. Not going to tempt fate. I SHALL use the chaps.
