These are the same Genes I made back in January/February 2012
Unfortunately, that original picture didn't have balanced light and so you can hardly see the Genes. Well, by September 2013, I wasn't wearing them anymore because they began to look pretty tattered and worn (as seen on the far right) These are about the only pants I wear for work (plastics manufacturing for NIKE) and they definitely show it. Even the leather on the cuffs had torn quite badly.
So in October 2013 I put some proper reinforcements on the front of the legs and knees where the genes showed the most wear. I used pig suede for the leather this time because it has a particularly high tensile strength for its weight. Now I feel like I could wear them for a couple more years straight, at least.
