950 Fill power is the amount of cubic inches(16 cm3) that one ounce(28.54g) of down will loft to

it is approx 12% more warmth per gram than 850fp down.

Total weight: This is the approximate finish weight of the item.

Down fill weight: This is the approximate total amount of down fill that goes into the item. This is generally a very unreliable metric for comparing warmth between different products since different products have different sizes which may mean there more or less down per area. However it is better than just relying on the given temperature ratings.

Measured Loft: My measured lofts are as follows:

5*C = 4.25cm

0*C = 5.5cm

-5*C = 7.75cm

-10*C = 9cm
