Shearling flight jacket question - how much do the sleeves shorten from creasing on a new jacket?

[Abyss]

Hi all,

I'm getting up to speed on the shearling flight jackets (that ELC Irvin Flyweight is really calling to me) and was wondering how much the sleeves shorten from creasing after wearing on a new jacket. On an A-2, I typically see anywhere from .5 to 1 inch. What about the shearling jackets?

Also, does the shearling stretch a bit after wearing like a goat or horse A-2 does? And, how much does the wool fleece compress after wearing?

I appreciate any assistance given!

The sleeves on my shearlings haven't got any shorter. Nothing has been stretched either. I haven't noticed any compressed fleece either. Perhaps the jackets have to be worn for many years before this happens. My oldest shearling is only a few years old.
