Just a thought, and I know we're in the dead of winter - unless you live Australia or New Zealand, obviously - but would an A-2 make good mid-weight summer jacket? I've got a really light-weight, unlined cafe racer that does as a windcheater but starts to change colour the moment a raindrop hits it, and we all know what happens if you get a suede jacket soaked. So, would one of, say, Aero's off the pegs make a good pull-on into spring/summer in case the skies open, or would it still be a bit heavy? Would steer or horse make a difference?
