The Hammer Straight - Old Blue Raw 10.5oz Selvedge

SKU 301154005-29

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.

Vintage Blue

These fit great, and I'm expecting some interesting fades with this vintage blue. The color is amazing, it reminds me of the jeans my grandfather used to wear at the farm. They've quickly become my favorite pair. I am strongly considering getting another in this fit, with a different wash. I've done one initial soak and have been wearing them pretty consistently, I'm excited to see how these age over time. They're already incredibly comfortable, but they feel like they'll break in really well.

Designed perfectly

I had some delivery issues, but HK sorted them out. Having recently discovered the brand, I’m impressed with their overall quality and attention to detail. I recently purchased the same color in the “Pen” slim. They’re a heavier denim 14. something oz. I liked them, but thought I’d try the “Hammer Straight” for a more relaxed feel. I can chalk this purchase up as a win and I’m inclined to grab a few different variations of them. I’m not one to review, but these are deserving…

Very very comfortable and great looking!

This is my first pair of Kato Jeans, after wearing Gustin straight fit for years. What an upgrade! The straight fit on the Gustin's is a little snugger in the thigh, so I had to get used to that but I quickly noticed that the little extra in the Kato thighs made these jeans sooo much easier to wear. And the silhouette on the Kato still looked great, not baggy at all, very nice. My wife thought the Old Blue color and finish of the denim looked "like really nice jeans", so there's that as well. Now that I've experienced stretch jeans, I don't know if I'll ever go back! My only feedback is I wish they were a little longer - I'm about 6'3" and I prefer to wear my jeans cuffed but with most of my of my shoes, I need all the length I can get. Great jeans, will buy again.

Thank you for the great review, Adam! We hope to continue meeting all your expectations.
