The Pen Slim - Black Raw 10.5oz Selvedge


Slim fit, medium rise, 10.5oz black raw Japanese 4-Way Stretch Selvedge, zip fly, premium leather patch, and custom-branded hardware. Made in USA.


Our premium denim is inspired by the classic vintage blue jean. Our Premium Japanese 4-Way Stretch Selvedge denim story starts in Japan where our fabric is developed at one of the oldest denim mills. We blend a unique 4 way stretch material with selvedge denim to create a specific amount of stretch and comfort you wouldn’t typically get with selvedge denim. This 360 degree of stretch gives the wearer comfort from every angle no matter what they are doing.

Our 4-Way Stretch selvedge fabric is weaved using vintage shuttle looms. Rolls of denim fabric are then brought into our workshop in Los Angeles where each pair goes through a 60 to 90 day process of cut, sew, washing and testing. With 4 fits available in multiple weights (see fit guide) and washes, the style options are endless.

Too tight

The waistline and crotch area is not forgiving at all. These pants run small and feels extremely uncomfortable. Zero stretch and a waste of money not to mention the length is extremely long. Great for 5% of who are 6 "4" +

Hi Miles,

Thank you for trying our product and sharing your feedback. We're sorry to hear that your experience didn't meet your expectations.

It's important to note that raw jeans typically feel tighter than washed jeans until they've had a chance to break in, which can take a few weeks of wear. Our jeans include a 4-way stretch to enhance comfort, but it seems we missed the mark for you this time.

We apologize for any inconvenience caused by the lack of an inseam option. We offer a paid hemming service to help customize the fit and hope this might be a helpful solution for you.

Best regards,

Jonas Jenkins

Poor customer service

The first pair I ordered were too tight around the waste. I tried them on once and sent them back. Some small scrap of nothing that I hadn’t noticed got on the pants while I was waiting to ship back. I ordered a new pair in a larger size in the meantime. When my return arrived the company told me they would not accept them back and now I’m stuck with a pair of expensive jeans that don’t fit. Will never shop here again.
The jeans themselves are fine but nothing special. They also collect lent nonstop.
