RemoteMedicAdventuresI've never seen 850 fill down from duck, is that even possible?

DannyMilksIf they study hard and apply themselves, there's no reason ducks can't achieve 850.

DannyMilksEnlightened Equipment's 850 fill is duck down. You get goose at the 900 fill level. See their FAQ below:
"A 20°F rating is always 20°F, but by moving to 900, or 950fp, less down (by weight, not volume) is used to achieve that insulation rating. Enlightened Equipment uses Gray Duck Down (GDD) for our 850fp option, and Gray Goose Down (GGD) for our 900 and 950fp options. Other than the fill-power, there is no performance difference between types."

That being said....Is this goose or duck down? I am not allergic to goose.

RemoteMedicAdventuresThanks again for asking. I looked into this and it is white duck down.

BronxCheerThis is white duck down.
DannyMilksDannyMilks, I appreciate you looking in this for me! I usually avoid duck down because it does have a reputation of smelling like a wet dog when it gets wet. Performance isn't necessarily the issue. I went ahead and snagged two of these up anyways! Thank you!

RemoteMedicAdventuresHappy to help and thanks for asking.
BronxCheerThank you as well. These forums volunteer so much more information than anticipated. Makes this piece of hiker trash really happy.

RemoteMedicAdventuresGoose can smell that way, too, but less often it seems. It's an issue of cleaning and if you ever get some gamey smelling down, a laundering will usually fix it. If it doesn't, then an overnight soak in any enzyme cleaner (unscented preferred) with some hand agitation will do it. 850 duck down is kind of a farce. Several years back "they" changed some of the processing and testing methods which resulted in higher fill powers for the same products/grades, especially when using the US method of testing (as opposed to Euro norm, China, Korea, Japan...not all on the same page yet). This isn't the first time this has changed in the down industry. In the 90s, 650fp was considered the top fill in mainstream products, but then processing changed and presto, we had 750fp (same down). In real life use, especially if your down is US graded, you can expect less loft than what they can achieve in the testing lab, more noticeable in the higher fill powers and mixes that use the highest 95/5 content (which is about the best you can dependably get, despite any marketing claims otherwise, including the oft-stated 100% which is cost-functionally impossible at this point). It doesn't make it bad or inferior down, just be aware of the numbers game the industry has. I think it was long agreed that duck maxes out about 700fp or slightly better (normal ducks, not eider) for most species and as it is commonly available in terms of the age of the birds. Duck down does tend to cling/clump a little more, which is compounded slightly by "dry" treatments, so using a little more of it and/or altering baffle widths can help it perform its best. You can get goose that is pretty much the same as duck minus the extra cling, but most goose is a bit larger and loftier - just depends on what the maker buys and then what the maker actually receives in the bales.

StepbystepThanks for the thorough explanation of this. It's awful to walk through some retail stores where rows of down jackets and sleeping bags smell like dirty birds. I noticed that Eddie Bauer, Western Mountaineering and Feathered Friends have consistently odorless down products so I tend to stick with them. My GoLite sleeping bag is unoffensive, too.
What type of enzyme cleaner do you use? Also, what do you do to clean down products with DWR?

BronxCheerFor this, really any enzyme cleaner will do. For tougher things like cat urine there are some products that work better (i.e. acutally work). Any good sports/tech soap will be fine for laundering (Granger's, Nikwax, McNett, etc. My favorite is Atsko but it's harder to find these days.). Just avoid normal laundry detergents since they are harsh on dwr and are hard to rinse clean (leaving residue which feels icky and also degrades dwr performance and/or breathability). Old fashioned original woolite works ok, too, if it's all you have available. Used that for many years before tech soaps existed and it did fine. You don't need a special "down" soap...mostly marketing blurb. For raingear I do prefer my usual Atsko or Granger's since both have been shown to be the gentlest on dwr coatings while being really effective at cleaning, but it's not a huge deal.
