FP Hydrophobic Down
Fill Power (FP) is a measure of the expansion ability (lofting) of down. Higher FP down traps more air is warmer for its weight.
Hydrophobic downs han been treated to absorb less water and dries faster than standard down, helping to retain loft and warmth in damp conditions.
The Responsible Down Standard (R.D.S) ensures the downs comes from ducks and geese well treated with an audited chain of custody from the farm to the product.
