Ordered an Eddie Bauer 0 deg bag yesterday, EB emailed me telling it has 27.66 850 fill down. Wondering if this is enough for a 0 deg bag.

It would help to know if that rating is 0 degrees F or C.

It would help to know what size it is (short, regular, long).

It would help to know what form it is (mummy or otherwise).

They call it 850 fill power down, but they do not specify the loft. Hmmm.

The link to the web page doesn't provide any information about the loft. That could mean any of a few different things.

1. They are trying to hide the loft number since it is not the greatest.
2. They did not include the loft number since they don't think that the customer would know what that meant.
3. They don't even know what loft means.

If Eddie Bauer is putting its label on it, it is probably not a complete piece of junk, and especially for that price. Maybe somebody else here knows it.

Do a quick comparison against companies that publish their fill weights that are also EN tested. Sierra designs publishes their fill weights, so does Western Mountaineering (a gold standard to compare against). Bob, loft isn't an end all, and is only one of many factors you have to take into account when determining temp range.

Here's some links to WM and SD bags:

So per, WM bags (which use 850FP) you're more inline with a 5degree bag. But of course, the fit of the bag can also have a large effect. But I wouldn't worry too much, you're in the right ball park and you can always bridge the gap with layering your other insulation.

"Bob, loft isn't an end all, and is only one of many factors you have to take into account when determining temp range."

Konrad, what specification would be more meaningful than loft?

Loft is one of the few specifications that an ordinary consumer can check while in a sleeping bag showroom.

If down is distributed suboptimally in a sleeping bag, you get cold spots.

Wait a second. If the bag was ordered yesterday, then wondering about it today doesn't really accomplish much.

"Konrad, what specification would be more meaningful than loft?"

Down fill amount and fill power. Too many variables go into loft, including baffle height, baffle width etc. I'm pretty sure there is a BPL article floating around here stating that loft isn't a reliable measure.

Also, from Richard N.,creator of the infamous new paradigm of warmth chart, "Trying to determine the warmth of a garment by just measuring its loft is a measure of futility."

"Loft is one of the few specifications that an ordinary consumer can check while in a sleeping bag showroom."

I would hope product reps would be able to give you fill weights off hand, otherwise they aren't very good at their jobs

"If down is distributed suboptimally in a sleeping bag, you get cold spots."

If you don't have enough down to begin with, you are just left cold.

"Wait a second. If the bag was ordered yesterday, then wondering about it today doesn't really accomplish much."

You can always return stuff, even used in the case of EB

Like others have said that is somewhat of a variable due to the fill power and size/cut of the bag. I think you said this has 850 fill power so lets look at some comparisons

Marmot Calour 34oz 800fill
Marmot Lithium 31oz 850fill
Feathered Friends Snowbunting 25.3oz 850 fill (narrow bag)
Western Mountaineering Antelope (5*F Bag) 26oz 850fill
Mountain Hardwear Phantom 0 28oz 800fill (narrow bag)
Mont-Bell Super Spiral 0* 30oz 800fill

So I would say it is in the general ballpark of other 0* bags, maybe more of a 5* bag. Of course only you can decide if that is enough down for you at 0*.

I saw it as a good value bag and hence purchased it. For $269 I thought it was a good buy specially with 850fill and Pertex Endurance fabric. Dimensions are L 78" x W 33" (Torso). I will wait for it to get delivered and return it if I don't like it.

Its EB … you can return it a few years down the road if they are still in bizzness … and they wont care one bit ;)

Eric, you are right, but after buying bunch of stuff from EB. I have a soft corner towards them. I think they just make of the best functional gear for affordable prices. I want them to make some money and stay afloat :)

Reading now bad other companies (MB , RAB cough cough) treat their customers once they sell the product, we certainly need EB, REI, OR kind of companies to be in business so that people benefit.

I have to disagree with RAB. I had an event jacket I had bought used that begin to delaminate and they replaced it no questions asked. They treated me fantastic.

GoLite's 4-Season Adrenaline bag (rated at 0F or -20 C) uses 23.2oz of 800FP down. It's a really slim cut though.

PostedDec 23, 2012 at 3:27 pm

You would need approximately 25 to 27 oz of down, depended on cut.

PostedDec 23, 2012 at 4:10 pm

EB bag is not slim cut for sure, and they have ridiculously decided to size it in a weird way, where a short bag is still 78" in length. I got a confirmation from EB that all three lengths contains same amount of down. I found one video of a 20F bag on youtube and the loft looks really nice. Can't wait to get it next month and try it out. For $269 I still think its a steal, I paid pretty much same money for my MB 30* bag :)

"EB bag is not slim cut for sure, and they have ridiculously decided to size it in a weird way, where a short bag is still 78" in length. I got a confirmation from EB that all three lengths contains same amount of down."

Those two points suggest that the Eddie Bauer information is not completely accurate. They must have had the information for one size, so they just applied it to three sizes.

Normally a short bag is for a person of maximum 5'6".

They definitely did not apply the same measurements of one bag for all sizes. Here are the specs of the bag's measurements directly from the website:

Dimensions: (Regular) 84"L x 33"W, (Long) 90"L x 33"W, (Short) 78"L x 33" W

Keep in mind we are talking about a 0 degree bag here, not a 3 season bag. It's likely that EB generously sized these bags because of their intended use…high altitude mountaineering most likely. In these situations you need extra length to stuff you boot liners, fuel, electronics and other widgets into the bottom of your bag, otherwise they freeze overnight. I admit, seems a even a bit long for that purpose, but it's still a possible explanation.

I do think that it's off that they all have the same down fill…I would venture to say that that info is incorrect.

use it and dont worry about it … if it doesnt meet your needs EB will refund or exchange it to your satisfaction …

its called a "what me worry on BPL?" purchase …

FWIW – I just ordered a 0 F bag with 31 oz 850+ fill. Dimensions for comparison are 72" long with 62" girth at the shoulders, 55" at the hip, and 40" at the foot.

Based on limited online research, I expect it to be fairly (if not conservatively) rated.

I plan to do a review after a couple of trips.
