anyone knows some characteristic of those two leather ?
RW IR 8111 vs 8115. leather differences between amber harness and copper rough & tough?
Here's a discussion about the two:
And here's some great comparison pictures:
I have the Copper Rough and Tough. I love them. They age really nicely. Comparing the two (I've looked at them in a Red Wing store), the outer surface of the Amber Harness are a little bit smoother.
Hope that helps!
