Nikwax Down Proof adds durable water repellency (DWR) to your down filled garments. Down is an amazing natural fiber for its compressibility, resilience, and warmth. The major drawback of down is its inability to retain loft and insulate when wet. To add water-repellency to the whole garment—shell, down, and inner lining—use Nikwax Down Proof.
This stuff ruins sleeping bags, because now it's like sleeping inside of a plastic bag. No breatheability. There is no reason to add water proofing to the outer fabric, this is for jackets, because we don't get our sleeping bags wet. My bsg is heavier now and it's not soft anymore.
