We are happy to offer custom sizing at no extra cost.  One thing to note is that a custom size is a final sale item (not eligible for an exchange or return).  

With that we ask that you take some careful measurements to ensure that the jacket you select will be the proper size for you.

If you provide your height and weight that’s also helpful if you need an opinion.

Once you’ve verified your size, you can make your purchase and then you can add your measurement request to the text box at the final checkout screen and/or simply follow up by email with your order number.


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 6-8cm (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.

If you have any questions along the way, please don’t hesitate to reach out. You can email us at info@mastersupply.co and you’ll receive a response within 24hrs.
