The denim is dyed with Indigo. One characteristic of Indigo dyes is the beautiful fade that occurs naturally. We suggest you do not wash your jeans for at least six months so you give the denim time to mature and adapt to your body.
Here are a few tips when you are washing and drying your denim:
Our heavy, raw denim is not washed, but it is sanforized to prevent major shrinking.
(NOTE: The amount of shirking varies depending on how the denim is washed and dried.)
You can expect around 2-3% shrinkage after the first wash. Please take that into account if you are going to hem the jeans. We suggest you hem the jeans either after the first wash or take the shrinking into effect when you hem them.
The numbers on our size charts are measurements taken after the first wash.
Sanforizing is pre-shrinking the fabric to limit further shrinking to less than 2%. If the denim is not sanforized, the denim can shrink up to 10%. During the sanforizing process, the denim is first shrunk, and then stretched to its final size.
Sanforizing also makes the fabric stronger as the fabric contracts. This creates durable and strong jeans.
