I own three of a competitor's product but have, today, purchased a Schott 257S in Ebony. Always keep an eye on where your jacket is. Someone with ill-intentions, that can spot quality, will note this and could possibly pick yours up and be gone in an eye-blink. Schott has a reputation for quality sheepskin/shearling jackets so I'm not concerned in buying this without being able to try it on first. Yes, well-made shearling B-3 jackets will keep you very warm and comfortable in temperatures ranging well below 0°. Best wishes with your new jacket, young fellow.
It's been awhile.. 7 years worth of whiles actually, since we did this video, but we think it's 42 (in the American sizing). Equivalent to the European 52 suit jacket size. The model is around 175 cm tall, average build. Hope this helps.
