[pct-l] Warm Jacket

[hochhut at web.de (margarete hochhut)]

Dear All,

Uff, I need a new warm jacket. I mean WARM Jacket. 
Plan to order the famous DriClime Windshirt. That won' t be warm enough in the camp, I am afraid.
What do the experts recommend to carry together with the mentioned Windshirt :

The Western Mountaineering Flight Jacket ?  Oooh, looks very bulky. It doesn' t look as if it can be worn underneath the Windshirt.
or
The Ultra Ligth Down Inner Jacket ? I' m not sure if that one is warm enough but nearly half the weight of the mentioned Flight Jacket.

Sorry for this question - I know everybody has another "Temperaturrange" for feeling comfortable. Nevertheless, I appreciate 
if somebody would share her/his experience with me.

Thanks for help
