850 FP Untreated Goose Down

850 FP Untreated Goose Down

850 FP Down is the best "Bang for your buck" when it comes to the DIY Indsutry. This down is most commonly used by those who want to strike a balance between superior performance and affordability. 


White goose down should be chose when using light colored shell fabrics such as white, light blue, or light greens. The performance is exactly the same between the two colors, but this ensures the stuffing doesnt affect the cosmetics of the finished product. 


Like all the down we offer, this down is Responsibly sourced and is BlueSign® Certified. For more information about these accolades please visit our resources page.

    Great down, exactly as ordered, arrived promptly. Used for light weight double quilt to replace 2 sleeping bags* - along with no zips and very light weight material this fully baffled quilt has halved our warm cover weight. Very warm 5cm of loft, good for subzero temperatures. *High quality sleeping bags but the 850 down is higher quality along with the quilt being self-sewn means the quilt is less than half the price of the sleeping bags.

    I love this company !!! The down is always clean, light and fluffy. Packages arrive quickly and they go out of their way to make sure it's exactly what you want. I've ordered before and will likely order again.

    I've ordered down from several sources over the past couple years. Not only is your price the best I've found, but the quality is noticeably better. other suppliers seems poorly sorted, very clumpy with much more feathers. Thank you for what you do.

    Excellent service and value. I successfully fortified a 70's Frostline Kit parka with an additional 9 oz. of 850 FP HyperDry-white goose down. The parka is now puffed out with great loft. Will be using in Antarctica.

    Just finished stuffing my ultralight hammock under-quilt and love how it turned out. I bought the 900 FP down 8 oz option and the loft is amazing. It even had 0.5 more oz than listed! Thanks Loose Goose!

    Tore a small hole in a nice, lightweight down jacket and lost down from a section. Very happy with the quality and amount of down I received. (didn’t know how much 850 down was in an ounce). I’m going to stuff a bit of down back in through the rip and seal 5he hole with tenacious tape. $10 of down to save a $300 down jacket! Very happy!

    It's easy and fun to make ethical down pillows with precision squishiness. Loved working with this company.

    Excellent 900 fp down. Easy to order and quick delivery. I appreciated directions for care before using it my project.

    I brought one pound of 850 FP HyperDry™ Goose Down. It arrived very quickly and the quality of it compared to another online retailer who sold the so-called 900 FP down is so drastically different. This stuff from Loosegoose is fluffy, lightweight, and will keep a person warm.

    I purchased a pound of 850fp DWR treated down to create a 30 degree quilt. Sadly, my delivery was stolen from my front steps. I notified Loose Goose and within 24 hours they had shipped out a replacement at no charge. I was delighted by their customer service and highly recommend their product.

    You guys delivered once again, and early to boot. Highly recommend Loose Goose for your MYOG/DIY Projects. Thanks again. Will order again when the time comes.
