This.
I have two cold weather jackets: one an unlined nylon shell with zip-off sleeves. Until the temps stay below freezing, I usually take the sleeves off and wear it as a vest over a long sleeve wool jersey and silk long-john top, otherwise my arms get too sweaty. The other is a fleece jacket with nylon windbreaker material on the front chest only. This allows sweat to evaporate off my back while still keeping me warm.
