Clampdown - Japanese Selvedge Denim Shirt

(9 reviews) Write a Review

Our Clampdown double chest pocket shirt in 10 oz. Japanese selvedge with corozo buttons.  We consider this shirt, given the weight of the denim, to be a "shirt-jacket", therefore it runs big.  Spec measurements here. Made in San Francisco, Calif. USA.


Nothing fancy about this shirt. Several buttons, two pockets. Right side pocket has a bit of a hidden knife slot.  This is just fine with us and we have always felt the need to stay away from trying to create the next and greatest new anything, so we take pride and comfort making shirts that could have been made 50 years ago.  No nonsense, just a well-built shirt made to last. This new Clampdown Selvedge shirt leans on the heavy side since we chose a 10.5 oz. fabric. It is a bit "slubby" but not to the extent that you feel like you need one of those tape rollers to start your day.

Thanks for wearing pants, and shirts...

    Clampdown Japanese selvedge denim shirt

    It’s tellason so quality of materials, craftsmanship, and customer service is just head and shoulders above everything out there. There’s no fluff just straight personalized nineteenth century handmade industrial quality. It’s sort of like if your friend worked at Levi’s in 1954 and went in and took care of your order personally or something. On this item the size runs one up so the medium is fit in the shoulders like a tellason large clampdown shirt in chambray.

    Heavy denim just right

    I ordered my regular size XL and it seemed big enough to size down to a large, so the boyz at Tellason sent me a large to compare fits.. Stayed with the large for a tailored fit, I’m 6’ 1” at 230 lbs. The back and front length hit perfect and the sleeve length has extra length for some nice wiskering. This shirt is loaded with dark indigo, and the fabrics weight is sure to grow this shirt to be a timeless piece.. It's filled with yarns to create a slubby appearance filled with just the right amount of little popcorns left behind through out the denim. Designed and manufactured to pass the test of time, and one to hand down for generations, I say. Love the triple stitching down the inside of the arms and side seems. Thanks also for providing that extra button Incase to ever loose one. Glad to own this one, it’s gonna produce some bitchen fades, I can tell already by the amount of ink transfer. Love it, when my hands turn blue!

    Very high quality throughout ever detail of this shirt. I am doing this review for not as a first time purchaser of the clampdown shirt but this most recent order was for my second. The first one I’ve had for probably 7 years and quickly became my go to shirt for all occasions working its way through to becoming an everyday work shirt for probably the last 3 years and has preformed excellently and continues to preform excellently. There is something the makes work more enjoyable about wearing something of such high quality and made by people who believe in the old standards that have been lost in this disposable nation we have created of quantity and not quality. The shirt is quality. Always by quality. That’s why I choose Tellason

    Really happy with this shirt, the length in particular. Extends down past the waist and is constructed with great care. Looking forward to wearing in and would definitely recommend to anyone thinking of purchasing.

    Not all denim shirts are created equal...

    I could not be happier with this shirt. Solid sewing, brilliant material, attention to the small details well managed. I am 6'1" and 175lbs and the large is just right. 'nuff said.

    Usual High Quality, Get It While You Can

    Highest quality fabric and construction, great fit. The Cone Mills denim ages so beautifully, I have a pair of four year old jeans faded from black to grey and the weave is so tight, unlike any other fabric I’ve seen. Look forward to wearing this for years, it’ll get better and better. Do not pass it up; you’ll get what you pay for.

    Comfortable and well constructed.

    This shirt is very well put together. Looks to be a double lined yoke which feels great along the shoulders. Stitching is neat with great attention to detail. Looking forward to wearing it for years to come.

    Excellent shirt

    Posted by Unknown on 5th Feb 2018

    As someone who looks to buy a solid shirt that will last more than 4 years I’m hoping this will hold up. One month of heavy use and one wash its still nice and stiff. I’m 5/7 140 lbs, and the M is a perfect slim fit. I see on IG they’ve noted this is 9 oz denim, not sure why it’s not in the description here, but good to know when comparing to the slightly cheaper 7.5oz shirt.
