Really? The point of this forum is that we are not at 27000 feet and we go over the details at 27mm most if not all guys who did wear them at 27000 feet almost certainly didn't give a fig about.A B3 is a B3 and at 27000 feet you were happy with a B3!!!
If you're happy with a Five Star jacket then fine its your money and your choice. I don't want one, thank you.
