i aM yOu...so to speak
hi, glad i saw your post...i just got a new black 184sm, which is totally differently sized than a 184sm from just a year or two back...
i saw all the measurements on the 184sm's on ebay, and when ordering a new one from a reseller i ordered a 46 (i actually have a 45" chest, 46" when expanded...am 6', broad shoulders)...but at the last minute i emailed schott to ask them about their sizing, and they told me the size 44 regular had an armpit to armpit of 26"...so i redid my order from a 46 to 44 and glad i did...apparently the older 184sm's were a full size smaller
the 44 is the perfect size, a little roomy in a well-fitting way...definitely room for a sweatshirt or sweater...HOwEvAH...i am only 180 pounds and have a 34" waist...so that may play into whether you think you need to go up to a 46
the jacket is amazing...i didn't want to get it because it wasn't authentic military spec anything...but then i accepted it for what it was, a classic post war motorcycle jacket, i had just fallen in love with the design, and i love it more now that i have gotten it...
at 6ft, the 26" back (neck seam to bottom) is sized well, but any shorter, or me any taller, and it would be too short...you didn't say how tall you were, but keep that in mind...26" back regular, 28" back for the long
lemme know which one you choose...i go the black since all my a-2s and g-1s were brown...i adorrre it
