Classic Slub Denim
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.

This wash emulates denim that has been worn for several years. Close attention has been payed to the slight distressing of the front and back pocket edges, to reproduce the wear seen on authentic vintage jeans.

Philip Green
great jeans

these are really soft and comfortable. they were my favorite because of the wash (1970's levis) until they went into the dryer (not my fault). they're perfect. I've been trying little by little to stretch them back but I think it's too late. waiting for the restock!!

Thank you for your review, Philip! We're glad to hear that you love the soft and comfortable feel of our Pen Slim Natural Slub Indigo jeans. We're sorry to hear that they got damaged in the dryer, but don't worry, we'll be restocking them soon.

Beautiful wash that makes these guys look so authentic. One of the most comfy non-stretch that I own. I’m between size 32-33 and 32 fits perfect.

Thank you for your review, Matt! We're glad you're enjoying our non-stretch jeans.

These jeans are perfect! Classic color, not many brands offer button fly which these are and the fit is amazing. I have these and a pair of Hammer Straight and I wear a 34w in the Hammer and a 36w in the Pen Slim. Hope that helps with any sizing issues. Get ‘em!

Thank you for your review, Chad! We're glad to hear that you're happy with the fit and the color of these jeans.

Love Kato jeans

Second pair of katos I’ve gotten and I love them. My first pair had the four way stretch so these did take a little bit of wearing to break in but they are extremely comfy now. Definitely getting more

Hi Tom, thank you for the great review! We're glad you're happy with both jeans. We hope to continue meeting your expectations.

My favorite jeans … ever

Just got my Lou’s a week ago, and they are already my fave jeans ever - and I’m 66 years old! Love the cut, the fabric and the fade. Even better than the 501s of my youth.

Thank you for your kind words, Mr. Howser! We're so glad you're enjoying your new The Pen Slim Natural Slub Indigo - Lou 12.5oz Selvedge jeans.
