In reply to georgewhyte:
I am a big fan of Buffalo for winter.
It does, for me, need to be below freezing to use it.
Last year I bought a long sleeved Brynje. Wonderful buy.
It is very warm but if I become warm and need to vent, the holes make venting more effective. It keeps me much drier than other synthetics and avoids that clammy feeling that I get with Jose Mourinho wool.
Used it last winter under a Rab Vapourise top and that is an excellent combination.
A lighter unlined windshirt would enable the top to used without the Right Freds Dead look mentioned by Ashpreston above.
