In the past year I have purchased two new pairs of Levi 516 jeans. Both split in the same place, vertically beside the back pocket and one on the first wearing. The store (Marks Work Wearhouse) replaced them and then one of the replacement pairs split again in the same place. I took them in for repair at a dry cleaners and they told me that they receive lots of Levi jeans for repair, usually in that same place beside the pocket. They had three pairs in the store at that moment. The repaired pair just split again within a month, right next to the repair. I have been wearing Levi jeans for 50 years and all previous pairs have lasted many years and usually finally giving out at the knee. This is new. I think you have a problem at the manufacturing end.
