I have a Size Medium antique brown leather Schott Perfecto 585 Vintage Motorcycle Jacket that needs a new home. I got the jacket new 3 years ago and it's in excellent condition. It's been worn once or twice per year since then. I never wore it in a smokey environment nor do I smoke. No funky odors, stains, tears, or deep scratches. The satin lining is in perfect condition. [[[SOLD]]] I don't have a tape measure for accurate measurement but here's the info I got from Schott: 585 Medium Chest - 41" Back length - 28" Sleeve length - 35 5/8" sizing info on Legendary USA website: http://www.legendaryusa.com/ProductDetails.asp?ProductCode=585&Show=ExtInfo Schott sizing chart http://www.schottnyc.com/shared/siz...hartid=12&TB_iframe=true&height=120&width=650 I have broad shoulders and wear a size 42 coat. I can wear a shirt underneath and the fit is comfortable but a bit on the snug side. The bi-swing back really helps out in that regard. It would be hard to layer a sweater or fleece though. It should fit fine if you wear a 40-42 sport coat.
