well to revive this thread I had to revive my old jacket,the #$%* aluminium zipper had been crap for a year coming apart while riding ect so got a new nickle plated brass YKK zipper swapped out,so nice now great action to it,last ride it let go I had to wriggle out of it like a mental hospital escapee in a straight jacket and get it off over my head still half zipped up much to the amusement of onlookers,only 120 bucks Im happy.
