The Pen Slim Natural Slub Indigo - Raw 12.5oz Selvedge


Slim fit, medium rise, 100% cotton raw indigo 12.5oz Japanese Selvedge, button fly, premium leather patch, and custom-branded hardware. Made in USA.

These jeans are non stretch and take time to break in.


Kato’s respect for denim reaches back decades. Our years of experience and research resulted in our own version of the sought after denim of the 70s. This fabric has been crafted with meticulous precision to replicate the uniform texture of the faded vintage denim collected for the Kato archives.
To make this a timeless pair of jeans, we chose our straight cut, “The Hammer” and the modern slim cut “The Pen”. The 12.5 ounce, 100% cotton denim does not have stretch but it will break in and mold to you, making it a pair you will want to wear for years. We wanted these jeans to be vintage down to the core details, so we introduced a button fly, using donut style laurel leaf buttons, which have been acid dyed to give them an authentic aged look. We also added a pop of color with a red leather patch, our own twist on the original. We are offering several versions of the Classic Slub Denim that represent different stages of aging.

Raw Indigo - Although This denim has never been washed, it is sanforized, a process that takes out almost all the shrinkage. The Raw Indigo denim has been dyed with a medium shade of indigo, giving it the tone you would find on a pair of jeans made in the 60s. After a few washes, the indigo deepens and becomes more vibrant before fading. The even weave, combined with the rope dying process, is perfect for someone who wants one of a kind fades that reflects the wearer’s lifestyle.

These are awesome! Perfect for anyone who wants a pair of raw jeans to break (100% cotton) in and hates getting blue indigo everywhere— wore these with white t shirts and sneakers and no dye transfer at all!

Thank you for your feedback on our Pen Slim Natural Slub Indigo jeans! We're thrilled to hear that you find them awesome and perfect for breaking in as they are 100% cotton. We understand the struggle of getting blue indigo everywhere, so we're happy to hear that you didn't experience any dye transfer while wearing them.

First pair of KATO jeans that did not match description

I have multiple KATO jeans and was really looking forward to rounding out my denim wardrobe with these… unfortunately the pictures look very different than the actual product. The jeans have more of a light blue/white sheen rather than the blue indigo look on the models. I should have expected the natural slub to be considerably whiter, but it just seems like an awkward color that’s hard to match. I really want to like the color with hopes it will fade into what I’m looking for… but that’s a big “what-if”for jeans at this price point. The returns process is incredibly easy, so it’s not too big a deal.

…….that being said, I LOVE the feel and drape of my raw natural slub white 14oz non-stretch pen slims, and was hoping these non-stretch natural slub indigo 12.5oz would get close to that but in a darker, less casual color. Are there any plans for more non-stretch options?

Hi Yannick

Thank you for your honest review.
In general, we try to make the product photos look like an actual product, especially on mobile devices but we are sorry that it did not work as expected for you.
The non-stretch jeans have more blue-ish tone than other indigo pairs for vintage-ish look. My apologies if it did not meet your expectations.

Best regards,

david kendall
so so good

perfect. this is the exact cut I've been looking for in raw denim. i'm pretty lanky and the Pen isn't too skinny or baggy. and i can't believe they're made in the U.S. you get what you pay for. props to Kato and Field Theory in STL.

Thank you for your kind words, David! We're glad to hear that you're happy with the product and that it fits you well. We're proud to manufacture in the United States, we hope to continue meeting your expectations!
