Clampdown Chambray Work Shirt

(13 reviews) Write a Review

Clampdown work shirt.  100% cotton raw 5.5 oz. Japanese chambray.  Cut and sewn in San Francisco.


When it came time to design our second shirt eight or nine years ago (Topper was first), we wanted to put together a proper work shirt. Of course, Clampdown was a natural as the name of the shirt. The Clampdown shirt has two large pockets to carry pens, knives, kazoos, string cheese, bottle openers, screwdrivers, etc. We've always worn ours untucked before that was even a thing. In the past we've made the Clampdown in raw selvedge denim, various colors of heavyweight canvas and a few different plaids. Now we have it in a beautiful 5.5 oz Japanese chambray. This version has white thread and buttons. So when you start wearing blue and brown and you're working for the Clampdown, we recommend our chambray Clampdown for the blue part of your wardrobe.

    Great Shirt to have

    Posted by Manuel Velasco on 12th Oct 2021

    So I purchased this shirt in what I’ve always considered my normal shirt size of XL… These days as a starting point. The shirt fit perfect if you like the slim fit. I did the hug myself test and and way tight across the shoulders. Made contact with Tellason, received an XXL and perfect fit. I’m 6’1 at 230lbs. And the shirt is not baggy nor fitted. The fit looks clean enough that you could go to Church or do chores, all in it fitting comfortable if that helps explain looks and fitment. These guys know solid clothing, I always look for their new stuff coming out… I would have gave 5 stars, but that’s best rating. Not that the shirt is not deserving, I just think a great shirt like this deserves a heavier Oz. Content for rugged ass wearing.

    Clampdown - a well put-together chambray workshirt

    Posted by LynnK on 3rd Oct 2021

    As others have said, this is a nice fitting and well built chambray. I have a small (uh...large?) collection of chambrays, and this is a keeper. The fabric on mine was very boardy and starchy when I received it, but it softened nicely after a rinse in the washer. It's now soft, but substantial. For sizing, I purchased a large, and I am happy with this size. For reference, I wear a 40R sport coat, my chest measures 40" or a tad larger, and I have a 34-ish inch waist. I am 5'10" and weigh about 166 lbs.

    This is absolutely as nice as the comments say it is. Just first rate in every respect. Super comfortable and so nice I can’t wait to wear it. Amazingly super fantastic. I’m 6’0” 173# and often I’m between a medium and a large and I got a large and it fits perfectly.

    This is the version I've been hoping for. My favorite shirt in my favorite fabric. This chambray is amazing right out of the box and I imagine it’s going to age beautifully. I can see wearing this one everyday of the week.

    The perfect chambray

    Posted by Ian Milio on 14th Jul 2021

    This is one of my all time favorite shirts from Tellason. The fabric, fit, color, and construction are all exceptional. The white stitching and white buttons lend a classic appeal. The stitching is immaculate, with the sleeves and side seams triple needle stitched. The fabric has a soft hand and breathes well so it is well suited for warmer weather.

    Really great shirt. I’m a big guy and the xxl is perfect for me. The quality of the fabric is outstanding and the stitching is sturdy. I would definitely by again.

    Like every other Tellason product, just so well made - perfect cut and fit. It’s clear they take so much pride in their clothing. I don’t even bother shopping around anymore. Love these guys - 100% the best denim brand in the world.
