"New for 2023 we bring you the Ironhorse. It’s been a long time coming, and it fuses our love for all things western with a nod to the old-school American motorcycle culture. 

The Ironhorse is made with our popular 13oz selvedge denim and our classic full-grain cowhide.  The jacket is tied together with copper threading and is lined with a cotton buffalo plaid liner.

The Ironhorse is hand cut and sewn at our shop in Sialkot, Pakistan."

Please note that we do suggest that someone else assists you with taking body measurements. If you have any questions, please contact us at

The Model is 6ft tall, weighs 175lbs and wears size US/M

If you want to wear thicker layers underneath, we would suggest going a size up. But if you want to wear with thinner layers, we suggest your normal size. Feel free to email us if you're uncertain about sizing! We're here to help.


In order to select an appropriate size please refer to the detailed measurements information below. The measurement instructions correspond to how the exterior jacket measurements are taken.

We ask that you carefully take the 3 main measurements to determine your size (for most your chest measurement is the size determinant)

Chest, Bottom, Sleeve Length

When measuring your body please add an additional 6cm (if you’re generally an XL or larger please add a min of 8cm) to your chest and bottom measurements in order to accommodate for the jacket lining, a light layer of clothing and some room for comfort. If you want to wear a heavier layer please account for a few additional centimetres to your chest and bottom measurements.

Please ensure that you use a rope or sewing measuring tape (the metal retractable tapes aren’t suited for garments) and measure in centimetres as opposed to inches to be more accurate.

We recommend having someone assist you with taking your measurements.

For your chest (measure all the way around the largest part of your chest). Measure under your arms. Try to keep good posture and remain in a relaxed state.

Sleeve length (shoulder seam to wrist). Measure from the ball of the shoulder/tip of your clavicle down to where your wrist meets your hand. Sleeve length has a direct correlation with your height.

The “Bottom” measurement is more or less your (hips). Where the jacket falls. Again account for the largest area (including your stomach) as ultimately the jacket must zip/button past it. If your stomach area is larger than your waist, then use the larger measurement of the two as your “bottom” measurement.


Please note that our standard sizing on the website is based on the Canadian/US standard sizing guideline. If you are shopping from another country, please ensure that you check your sizing relative to Canadian/US sizing.
Our sizes are true to size with a slightly tapered silhouette.
If you’re looking to layer under your jacket, you may want to consider a size up. Although, naturally over time, and with wear, your jacket will begin to form to your body.

The size chart measurements are the measurements of the actual jackets. Please allow a +/- 1cm deviation as all of our jackets are hand made.
