The Pen Slim - Old Blue Raw 10.5oz Selvedge


Slim fit, medium rise, 10.5oz old blue 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.

This season we use our breakthrough 4 Way Stretch Selvedge as the base for several new fabrics that give a nod to the freewheeling vibe of the 70’s.

This denim is Indigo dyed to a light and vibrant blue. This color combined with the lightweight makes for the ideal summer selvedge. The denim features a faded red selvedge ID.

These jeans are the best ,I have a few pairs of KATO jeans however the color makes it unique and personal favorite. It pairs great with a white or black shirt , I would highly recommend if you wear white colored shirts often. Great for a night on the town, you will definitely receive a compliment with these on.

Only jeans I want to wear. Perfect fit. This is my 4th pair and am slightly obsessed so I'm finding it difficult not buying every color available. I used the hemming service and they do an amazing job.

Great Jeans

First pair from Kato & these are awesome. Great color, not too too vibrant, just the right shade of blue. Comparing these to my other Japanese denim jeans, I prefer these because of the stretch, they’re super comfortable and great quality. My only gripe is the customer is responsible for paying for hemming. I know most denim companies make these 34+ inches long, but I wish we didn’t have to pay for hemming. Other than that, all good and will purchase again.

Thank you for leaving a review for The Pen Slim - Old Blue Raw 10.5oz Selvedge. We're so glad to hear that you love the color and quality of these jeans. We completely understand your gripe about the hemming, and we will definitely take your feedback into consideration for future releases. We appreciate your support and hope you continue to enjoy your Kato jeans.

Surprisingly Great Color

These jeans are the typical outstanding quality of Kato Jeans but I was surprised how much I liked the color. They look like a modern version of your grampa’s jeans in the best way possible. Love them.
