Jeans made in 12.75 oz dry comfort stretch denim. The yarns have been yarn-dyed prior to the weaving to keep the yarn-core white. An aspect that allows for some serious break-in potential. We recommend 6 months of hard, every day, wear before the first wash, if not longer. This way you will end up with a beautiful pair of worn-in jeans. It sure is a long time, however, it's only a recommendation. As long as you give them love, the result will be great.
