How to find your Jacket Size.
1. Measure around your chest below the armpits. Leave a space of two finger widths between the tape measure and your body. Use this figure to determine your size using the above size charts. PLEASE NOTE: If you find yourself between sizes on the chart go to the larger size.
2. Bend your elbow, and measure from the side of your neck to the elbow and down to the base of the thumb. If this figure is larger than the corresponding figure on the "regular size" charts choose a size from the "long size" charts.
