What is down fill power?


Down fill power is a way of measuring the quality and effectiveness of down and feather. scooms Hungarian goose down duvets have high 700 fill power. The fluffier the down is, the greater the number of air chambers and the more effective it is at insulating. So a higher fill power provides a lighter and more insulating duvet. The duvet will also recover its fullness more easily when shaken in the morning and is more durable, so it will last longer.

Fill weight is the weight of the duvet filling. If you see weight referenced with ‘gsm’ this means the weight of the filling within a square metre. See the fill weight of scooms duvets.
