In reply to PPP:
So all of the superlight windproofs - i.e. that are actually wind proof, are some form of similar-to-pertex fabric. Some are more breathable than others - e.g. the Houdini Air is about 4 times as CFM breathable as the normal Houdini. Montane featherlites and the like are all 'windproof'.
What you seem to want is a thin softshell. Which are more 'wind resistant' than 'windproof'.
Good options include the ME Aerofoil, Rab Borealis, Arcteryx Squamish etc. If you want close-fitting sleeves, then I can say my Borealis (I had the pull on), is ideal for this. The hoods are all lycra bound so good when on if you zip the jacket up - and neither according to the website does the ME jacket. They're for mixed, windy but not very wet weather. Which, frankly, if you're running, is fine. You're gonna get damp anyway, because sweat. Mine doesn't actually have a DWR, but the modern ones seem to. Which is fine except that you're gonna strip the dwr washing the sweat out of it a few times a week.
