I tried it on at Antithesis the other day.
Wearing my J58-WS underneath here and very confortable even with my liner on. Still not a fun of the look of black portions fabric but I kinda changed my mind on this jacket. Fabric felt extremely thin and soft, very nice at touch. I do really like the collar, quite rigid in a positive way and it stays in place. First time trying Fidlock system and I like it, chest pocket locks in place immediately by its own when you put the jacket on.
