"-no one seems to make outdoor clothing for LONG TORSO women"
There, I fixed it.
My wife is short, and when it comes to pants, there isn't a single outdoor company that makes pants short enough for her, and she's skinny so that isn't the problem. Almost every outdoor pants out there for women have long enough legs that I could wear them at 6', even if they are half my waist size…
As far as your question is concerned, since she is close to your size, try on one of her other jackets that fit her well, then take note of the difference in fit to you. (e.g. sleeves may only go to your wrist bone instead of your hand, chest might be roomier, or tighter, than you usually wear, body length too short or long for you, etc.) Then try on jackets at the store, men's and women's, to try to find one that fits similarly.
