What filling details should be specified before sampling a custom down jacket?

Specify the filling type, declared composition, fill power and target fill weight separately before sampling a down jacket. Define the relevant test methods and conditioning for declared properties, and identify whether requirements apply to the filling material or finished garment. Include the intended size range and use conditions. A higher fill-power figure alone does not establish the warmth of the complete jacket.
