dgamage,
please try the dying routine and report how this turns out. It sure doesnt hurt to give it a try. You may be starting a new fahsion trend ,if nothing else. Did you ever consider dying it like a gray...just to try a change in color/atmosphere?
I heard that this is how Kim Kardashian got started in the fashion bizzz,,and look were she is at now?,,,

If you are happy with the way the jacket still fits,,, then go for it. I would guess the jacket will do whats it is suppose to do,,in the event of a layover. We are not going to the moon with this article of clothing,remember.
I think you have come up with a very standup idea here,honestly.
You are also going green in that the jacket will not be thrown in the local landfill after you throw it in the garbage can. Two thumbs up to you!
Take Care,
BC
