IceFlame Down Quality & Testing Standards
ICEFLAME submits down batches to IDFL for independent testing of fill power, composition, cleanliness, and other reported quality indicators. These reports help us verify supplier data and document the down used in production.

Odor Control
Our NXT and EX series use down sourced from mature birds (100+ days), resulting in naturally low odor and superior cleanliness.
RDS Certification
Using RDS-certified down adds significant cost, and we always strive to source responsibly whenever possible. However, for certain high-end fills—such as 900FP down—large-volume purchasing is not feasible, and the cost of obtaining RDS certification can exceed the value of the down itself. For this reason, 900FP down is extremely difficult to certify under the RDS standard.
At present, the 850FP / 900FP Muscovy duck down used in our products is fully RDS-certified.

Fill Power Index
IceFlame sources its down from exceptionally cold regions, where harsh climates allow geese to grow dense, high-loft clusters that deliver outstanding warmth and long-lasting performance.
Submitted IDFL test reports record results including 820FP for 92% white goose down and 700FP for 85% white duck down. ICEFLAME does not use chemical treatments to artificially increase the fill-power figures presented for these tested materials.
