I'm another happy user of a Novara Headwind jacket. Mine's a model from a couple of years back. Windproof front, breathable back. I'm not sure if they've changed it, but it's my most valuable piece of upper body wear. Here Minnesota I wear it almost half the year. With thin under layer, very good in spring/fall 40-50 degree days for me. Add a thin fleece insulating layer and I've ridden it down to 0 degree F. air temp (minus something in the teens wind chill, and of course on a bike you're also making your own wind chill). I thought the breathable back would be an issue for really cold days (0-20 degrees F) and would at first wear another jacket instead of the Headwind, one with a windproof back, until I learned to trust/prefer the breathable back even down to 0 F.
