Breaking in a denim jacket is an arduous task, and wearing it every day for 6 months won't cut it. However, there are ways to speed up the process, wearing it under a jacket or coat for instance.
Since April 2018 we shifted our production into using the paper-based material jacron for our patches. Now all our denim products are produced using the jacron patch. However, a number of our products will have stock of both jacron and leather for some time. This product is one of those and comes with a patch in either jacron or leather. Both do, of course, hold a high quality and are visually very similar.
