When should you wear a down jacket?
If you want a jacket to wear as an outer layer in extreme cold but dry conditions, then look for a box-wall down jacket with a high fill power and a generous total fill weight.

Why is down so expensive?
What makes goose down so expensive is that goose down is extremely difficult to obtain. Compounding its rareness is the difference in the quality of goose down produced by different aged geese. Adult geese provide the softest, most comfortable, and highest fill power down. Young geese provide low quality down.
