The Pen Slim - Indigo Raw Air 11.5oz Selvedge

SKU 3010-446-05-29

Heavily Textured, Lightly Worn

In the pursuit of innovation we have created our latest achievement in denim. The idea for Selvedge Air was born out of the love for old vintage denim and the need for comfort. We wanted to introduce a denim that had the look and feel of a 15oz denim but one felt light and very comfortable when worn. After a very long development process with a highly capable mill in Japan, we were finally able to make this vision a reality.

Instead of using the usual 3 X 1 weave of standard denim, we implemented a 5 x 1 weave. This creates a denim with a higher surface thread count but a lower overall thread count, making it lighter and still durable. The low tension yarns and loose denim weave contribute to the thicker look of the denim while maintaining its light feel. The overall result is a vintage textured denim that looks like heavy weight and feels like a lightweight.

• 4-Way stretch selvedge denim

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.


Crafted with intention, our denim is made using premium Japanese 4-way stretch selvedge in our Los Angeles workshop. Our denim goes through a time consuming 50 day process from start to finish to ensure the highest of quality. Built using only the best available hardware with traditional machines and techniques, you are getting a true vintage inspired piece with a modern upgrade of comfort.

No bueno

Massive amounts of shrink in the length on these. Had these hemmed about 1" too long so I could cuff them. Worked great until I washed them. They're now too short to wear even cuffed.

Not their fault but did try to reach out to them. Of course no call returned.

Steer clear.

Hi Tom,

We sincerely apologize for the disappointment you experienced due to shrinkage after washing. Unfortunately, we couldn't find any orders linked to the email associated with this review. Could you please share your order details with us at We're eager to address and resolve the issue.

Thank you,

A 50% fit

I have another pair of Kato jeans - 34 waist that fit me like a glove. Be aware that this cut is VERY tight in the hips and waist.
I ordered these in size 34 and there’s no way I could button them- even though they fit great in the legs and length…..
Had to size up to 36 waist - now that fits great - but the legs and length are too big.
For a premium price - I’d expect a premium fit- but it’s not the case with these jeans.

Thank you for your honest feedback. We apologize that the 11.5oz in size 34 did not fit you properly. Your insights will be shared with our production team for future improvements. We regret any inconvenience this may have caused you.

A note on the pen slim cut

This is my 3rd pair of Kato's. Love my first two, I've had them for a year and wear them all the time. Those two were hammer cuts, their the most generous cut. I'm 6'00", 184 lbs, fit (size 32). I agree with Alexander's comments below: The pen slim cut is considerably tighter around the hips and thighs than the hammer. I would go up a size if you're considering this cut and don't want to deal with an uncomfortable fit until they loosen up. Otherwise, top quality.

Thanks for the honest review and feedback! We're sorry to hear that you don't like the fit of the pen slim cut, if you're still interested in a slim fit we recommend trying out Scissors Slim Tapered. Thanks again for your review!

First (fit) impressions

Just received these and wanted to add some color since I was looking at reviews for fit info before ordering and had to guess on a few things. I've owned only a few pairs of selvedge so not a denim head by any means. As others said, quality seems super high. Don't have a great reference point tbh and time will tell on break-in and wear.

5' 8", 155#, athletic build with short legs/long torso, find 29" waist is perfect in most pants so ordered a 29". My true inseam is like a 26.5" so 27" with a slight break works for me usually. Went with a 29" hem assuming 1" for cuff and 1" shrink but find it's a bit too short for a cuff. Would go 30" or keep 33" and double cuff next time. As another reviewer said, I put these on and woof, thought I whiffed on sizing. Had to suck it in to get it buttoned. Kicking myself not going up to 30" but wearing around house for 10 minutes, waist stretched and I could get two fingers in. Wouldn't get too discouraged on first wear.

The only thing I'd watch out for here is the hip measurement, which is not included in the size guide. Even after waist stretch, the crotch and butt feels real tight, which ends up mashing your stuff up front. Feels like the pants is a bit more made for skinny folks with smaller hip abductor muscles. Rise is same as my perfect fit jeans fwiw. Again, hope to get some stretch but would just watch out for this if considering. Most athletic jeans/chinos brands I have give a little more room in the seat out of the box.

Fit is more straight slim but I tend to wear tighter jeans. Size guide is correct on actual measurements below the thighs fwiw. With a small inseam, tailored slim fit 32"+ inseam pants tend to taper weird due to the pant being made for someone with a longer inseam. Would go with the Needle next time as I like a bit more tailor below the knees.

Hi Alexander, thank you for taking the time to write such a great review! We recommend The Scissors Slim Tapered fit for our customers with a more athletic build and it has more room in the seat and thigh area. We truly appreciate you taking a change with our brand.

Really nice jeans. Top Quality.

Just received my Slims and what an amazing pair of jeans. Depending on the brand, I can be anywhere between a 32 and 34 so I took a chance and and ordered the 33s and they fit perfectly. The workmanship is topnotch, the looks are stylish, but not trendy. All in all, I'm very happy with the quality and service. Going to order their Blade coated indigo jacket while it's on sale.

Thank you for your review, George! We're glad you liked the jeans and the top quality of the workmanship, we'll be sure to pass the good news along to our team.
