How to measure.

Measure a jacket that fits

1. Chest: zip the jacket, lay it flat, measure pit to pit, then double that number.
2. Shoulder: measure straight between the shoulder seams across the back.
3. Sleeve: measure from the shoulder seam to the end of the cuff.
4. Back length: measure from the base of the collar to the hem.

Product tables use garment measurements. Your body chest is different. Allow extra room for movement and layers; if between sizes, compare all four measurements and ask us before ordering.
