Fill power is the space that 1 ounce of down occupies, resulting in its insulation quality: a higher number means bigger clusters, so the same amount traps more air (read: warmth) with less weight.

Product Care
Wash on a gentle cycle using mild soap. Dry fully with tennis balls to properly fluff and redistribute down
Machine wash in a commercial size front-loading washing machine. Do not use a washing machine with an agitator. Wash in cold water with a mild, low-sudsing soap. Do not use bleach.
Dry on low heat. Use tennisballs in the dryer to dissipate clumps. Dry well beyond the point where the outer fabric feels dry; this often takes 3 - 4 hours. This will ensure that the down clusters are free from any moisture.
If possible, allow the comforter an additional 24 hours to air-dry before placing inside a duvet cover.
