And who makes B2 @Aloysius ? I couldn’t find much info online
Lost Worlds, Buzz Rickson’s (previous seasons), maybe Good Wear (John told me he has in the past but I don’t know if he still does). It’s an insanely over the top jacket.
Some others (Thedi and RRL I think) do a sort of B-3/B-2 hybrid which you might be able to find more easily but it is a standard shearling jacket with the B-2 pocket setup.
