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.

THERE’S DOWN
Then there’s Downright


Your best night’s sleep
A comforter that manages your body heat and adapts to the climate. All for a rest so deep, you’ll be upset you slept through it.


Every detail indulgent
As high-touch as our fill is, you mostly come in touch with the cover materials. That’s why we invest just as much passion and effort into achieving the highest standards of fabric purity, quality, suppleness and durability.


Allergies, finally put to rest
We spare no effort to ensure you’re left with pure down that’s naturally hypoallergenic and safe for the entire family. Each comforter is sewn from breathable cotton sateen, then filled with down clusters that have been washed twice, rinsed four times, then tested time and again
