I live in Central New York state. I am looking for a period jacket that I can wear from ~40-45F down through high 20-30F to work wearing an undershirt, dress shirt, and tie, (no suit jacket) perhaps adding a sweater or sweater vest when below 32F. (I own a 1980s Avirex B-3 for colder weather, of which there is much up here, and a Cooper A-2 for ~45F and up.) I am torn between the ELC B-6, which is without a doubt, utterly incredible, and the WWII Impressions, "Uniform, Combat, Winter" - aka Tanker Jacket, which is, without a doubt, stylishly utilitarian. Problem is, I believe they both might operate well within my desired temp range, but there is that ~US$1000 spread between the two. This may end up being a matter of when in doubt between the two, buy both! Problem is balancing function, style, and, as always, cost. Any input, experience, comment is appreciated.
