Good points, and if your right this makes sense. I've been wondering why the leather would be thinner and the growth aspect makes sense. However the Zugs we received last year are made from thicker leather as well as my Viberg boots when compared to other boots I own. I guess getting thicker leather is still possible but just not as easy?? I've been going through the leather thread, I just haven't been able to find the topic of thickness of leather bring addressed yet.
