I don't understand why Aero line the cuff inside without leather. It's the only jacket I've ever seen or owned that does it. Fabric wears out and gets dirty and sweat stained. I can totally see why Insurrection Leather have all their custom Aero half belt cuffs leather lined.
News to me, Gray. So it should. Maybe Aero changed their approach to cuffs over the years.
What I don't get are jackets that have knit elastic cuffs, but with a piece of leather - about 1+1/2 inches thick, in between, where the knit cuffs seam would be. I used to have a flight bomber jacket like that...
