Spiewak N-1 jacket type Size S, equivalent to Japanese size M Fits perfectly for someone 175cm tall and weighing 70kg Size (Please note that there may be slight variations due to amateur measurements) Shoulder width: 49cm Body width: 58cm Length: 71cm Purchased approximately 20 years ago. I loved wearing it when I first bought it, but it's been tucked away in the back of my closet for several years. It has a great American-made feel, and although there are some stains, it's a tough outerwear piece that can still be worn well for years to come.
