    They’ve changed a quality product

    These trousers USED to be excellent. They have now reduced the quality of these and they are a lot thinner than my other 4 pairs I have. The material is different and when I received these I bagged them up and posted them back. This new version is poorer quality in comparison to the older version of these. I would not recommend them whatsoever.
