For cycling I've jettisoned all jackets and I've been cycling with a vest, even in the dead of winter (well dead of winter here in northern California means rarely colder than 40 degrees). A couple of layers of longsleeve merino wool keeps my arms plenty warm even if there is rain. I have to admit my Optik vest breathes really, really well and if it weren't for the very irritating and uncomfortable fit, I'd just stick with it.
