Leather black pants - thin warm fabric

Size: US 6, Europe 38. I did use it once but, I realised it was not my style. It was washed inside out to not damage the fabric. In perfect conditions. It is very flexible and it adapts perfectly to every body. The fabric is thin which makes it fresh for summer and, the inner coating and the leather itself do not allow cold to pass through in winter keeps you very warm (double-checked).
