Another vote for the Gaba. I got one towards the end of last winter. I've worn it with a base layer down to the mid to upper 30's. Alone to the mid 50's. It has two zippered vents in the front when it gets too warm. Does a great job with wind and a drop down tail for protection from road water. I think it's available with zip off sleeves although I don't have that model. I'm really pleased with it.
