iirc fok has said that a 1.5mm lamb is incredibly thick, his exact words being "1.5mm lamb is a lamb to kick all the other lambs asses." i believe their spec is 1.2, i'll post my impressions once i get my jacket.
debating between goat and lamb, more leather information please
how does goat age? lamb?
i had the old toj calf and that was far too thick/indestructible but afraid of the lamb being damaged on a night out etc
