Jeans made in our Japanese comfort stretch selvage denim. The fabric is modern, but it's made the old school way. We recommend 6 months of daily use for all selvage qualities; this applies to stretch selvage as well. However, this is only a recommendation, because there are no right or wrong ways to break in dry denim.
Since April 2018 we shifted our production into using the paper-based material jacron for our waistband 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.
