NOTE: The tables show the measurements of the garment itself.

The easiest way to determine the size you should order is to measure a garment you already have that fits the way you want. Lay your garment very flat on a table and measure across the chest, just below the armpits. That will give you half the chest size. So if your garment measures 24 inches across the chest, you would order a size Large (48.5-inch chest).

If you seem to be in-between sizes, we suggest ordering the larger size.

The sizing data here will be updated shortly with measures from the 2025 version of the SkiJac.  The sleeve is now measured differently than previously (was from point of shoulder).
