The Pen Slim - Ace 10.5oz Selvedge


Slim fit, medium rise, vintage fade Indigo Japanese 10.5oz 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.

Because our 10oz denim represents a modern denim fabric, we paired it with a higher contrast fade for the Ace, to emulate the type of fades you see on modern Japanese jeans. The Ace wash having the highest contrast and most defined creasing of all of our aged denim washes.
