One of our highest silk composition denims ever gets treated to a super nep yarn to make it a true work of fabric art. It's the complete package - classic roots, ultra rare ingredients, intense character. The Japan Silk Nep. We're having our partner mill make a limited batch just for you.
This is one sweet denim from start to finish. It's the perfect blend of rare ingredients, character and classic fundamentals. Japan is the master. Here, we start with pure luxury in the form of silk yarn. One of the highest silk compositions we've run at 42%. It's paired with a classic dark indigo dyed cotton. The result is instantly recognizable, classic raw denim with a level up in feel. You get the rawness we all love, but it's just a big notch more wearable. That wearability is great because you'll want to show off the super neppy finish on the surface. Organic and unique in each pair, the surface explodes with these tiny tufts of yarn. It lends the denim a hand crafted feel that sets it apart of anything else while not being over the top. This is simply special fabric you will feel and enjoy every day.
Choose either our classic straight, slim or skinny fit. More details available on our fit guide.

"Fits well after acknowledging to order a + size from my other jeans."
-Brian D. | Verified Buyer
"Wonderful material unlike any other jeans I own, and looks as nice as in the photos."
-Jason C. | Verified Buyer
"The jeans are extremely comfortable. The silk blend and lightweight fabric make them breathable and perfect for summer wear. Although I was initially disappointed that they weren't selvage, that was my oversight as I didn't realize Gustin now offers various types of jeans. The nep detail is stunning. Highly recommended!"
-Adrian A. | Verified Buyer
