My Patagonia coat
Kyrgyztan (near China) horse back riding.
If you debate with yourself if to take an extra jacket or "travel light" - this is your answer - take this jacket. It is so light and compact, that you still travel light. It's a shame, on Backcountry site they do not have a picture of this jacket as it folds into its own pocket. It becomes as small as 2 cans of cola. Nevertheless it is pretty warm. Comes very handy when it gets chilli...
I also found it very useful as an insulation layer for skiing. In combination (or alternation) with a thin shell it gives a lot of flexibility.
