View Full Version : Campmore 0 degree down bag...too good to be true?
Does anybody have experience with the Campmor 0 degree down bag (http://www.campmor.com/webapp/wcs/stores/servlet/ProductDisplay?productId=86902&memberId=12500226)?
It's only 139.97...
Can a down bag be that cheap but still keep one warm in the teens and below?
:D

1 lb 11 0zs down = 27 ozs X 550 fill power = 14,850 cubic inches of insulation. Sounds like plenty to me.
I've found that their 20* down bag is pretty well rated and rather than spend 2-4 times as much, wouldn't think twice about getting a 0* bag if I thought I needed one.
Frolick,
You do it this way for a close answer- Length x Width x Height( Loft) give cubic inches. Then divide by fill power should be close not including the taper of a Mummy bag.

Doesn't the fill power already represent volume? Like 550 fp= 550 ci per oz? Or something like that?

That would be implied by Dino's response (Msg. #2.) I always wondered what those down ratings meant, so thank you, FD.

Weldman - loft is often not known so I've always used this formula - total cubic inches of insulation divided by this: 1/2 of the length multipled by the top width plus 1/2 of the length multipled by the bottom width. For the Campmor 0 F mummy bag:
14,850 / {(40*32) + (40*20)} = 7.139 inches of loft
This gives me loft which I then plug into my own modification of the the 'Ray-Way' formula:
100 - (Warmth factor * loft (/ 1.75 for sleeping bags or .75 for quilts) = degrees in F.
Warmth factor = 35 for very warm sleeper, 30 for warm sleeper, 25 for average sleeper, 20 for cold sleeper and 15 for a very cold sleeper.
For the above example with an average sleeper:
100 - {25 * (7.14 (the loft rounded) / 1.75 )} = roughly 0 F

Hey, I had a buddy who bought this same bag and used it on several NC mountain winter trips and said it didn't keep him warm enough. He thought it sounded too good to be true at $139 but he went for it anyway.
We talked about it later and though 27 ozs of down sounds like alot(with hardcore mountaineering bags in the 35-40 ounce fill range), 550 fill can't compete with 800 fill and plus the Campmor stitching, seams, baffles and draft tubes and quality thereof might add to the problem. I would most look into their source of down and whether what they call 550 down is REALLY 550 down. Some bags have down that is more like a feather pillow than a true goose down bag.
BTW, what's the total weight of the bag?

Campmor's website says 3 lb 5 oz for the 0 deg. bag.
I took said bag on a trip this past weekend from carver's gap to 19-e temps in the mid-hi 30s at nite, and the bag was unzipped all nite. no cold spots, 'cept when my foot, arm, etc popped out.
I have the 20 degree bag and it has kept me warm on nights where my washrag had frozen solid as a rock. Good bag. I wouldn't think twice about getting the 0 degree bag.

I was thinking about getting a North Face Cat's Meow, 20◦, weight listed at 2 lb 11 oz and is $129.00, because I didn't want to worry about getting a down bag wet. Now I'm intrigued by this Campmor 0◦, same price, but it is heavier and I'm not sure I'll need the extra warmth since I'm not sure I'm going to be hiking in those temps; and there is the down thing. Anyone have any advice? Mainly the issue is down v. not.
Don't let down scare you. I hiked for two weeks in solid rain and never had an issue with getting my bag wet. Condensation got on the footbed a time or two but nothing serious. I keep a turkey roasting bag in my stuff sack and it works like a charm.

A 20* bag is the best all around bag. Unless you start very early it'll keep you warm most nights, if not all of the hike. On the otherhand, a 0* bag would be overkill after mid March and even then more than you'd likely need.

Go with the 20 degree down; keep it in a trash bag inside your stuff sack and it'll stay dry.

Best bet is to plan on using two different bags -- a heavier 3-season (say, 20 degree) bag for the start and end of your thru hike -- and a lighter summerweight bag for the middle of the hike (say, from Damascus to Hanover.) During the summer months you'll be fighting the heat, most likely.

I have this bag - can't vouch for at 0F but has kept me plenty warm in the high teens. So far has been good bang for the buck although I have not taken it to the rated temps.
Great info...Thanks everyone!

What exactly is this Ray-Way formula did a quick google on it and it wants to send me to ray-wave.

Hi,
If your interested in a 0 deg campmor bag, I have a 2004 6' L.H. zip that I'd like to sell. (Only used 4 bag nights)
$65.00 shipped ( it has a 2" tear in the hood, that I repaired, but this won't effect the function of the bag at all.)
I've slept in it at 5 deg and was warm. I bought a used WM Puma, so I really don't need (2) cold weather bags, anymore.:-?
