I have always wanted to know exactly what the fur on a winter coat hood does to help reduce heat loss. Lots of Internet forums are full of conjecture and theories but they all seem weak. I have finally located a good scientific explanation of why the fur is a thermal advantage. I invite you to read the following paper.
Effect of ancient Inuit fur parka ruffs on facial heat transfer From the paper: ABSTRACT: The traditional clothing system developed and used by the Inuit is the most effective cold weather clothing developed to date. One of the key elements used by the Inuit is a fur ruff attached to the hood, hem, and cuffs of their parkas. This paper determines why the fur ruff is so critical to the effectiveness of cold-weather clothing, especially in protecting the face, without impeding movement or view, so essential to the Inuit hunter. To quantify the effectiveness of this clothing, heat transfer was measured on a model placed in a subsonic wind tunnel. The wind velocity and angle to the wind were varied. A boundary layer forms on the face, and heat transfer was measured across that layer using thermocouples. Different fur ruff geometries were examined to determine which was most efficient. The experimental results were combined with data collected using ethno-historical methods since 1970 by 2 of the authors. The traditional headgear proved to be the most efficient. The lowest heat transfer was found for the sunburst fur ruff geometry at different angles of attack and wind speeds. This unique combination of scientific and traditional Aboriginal knowledge provides a holistic perspective on new insights into the effectiveness of cold-weather clothing systems. TL/DR : the fur disrupts smooth air currents and forms an invisible pillow of air between the face and the environment. |

Great post. And timely in my case.
I am Canadian. I grew up in Canada and all the parkas I had included the traditional fur (or faux fur) trim around the hood opening. For me there is no doubt that the fur improved performance in terms of wind resistance and corresponding heat loss. Living in Colorado for quite a while I haven't generally needed near the kind of clothing I needed back home to protect against the elements. It definitely gets cold here but to suggest it gets "Canada cold" is disingenuous/idiotic. Regardless, I recently wanted to upgrade my cold weather parka. Usually basic jackets would do but I wanted something for actual cold. The fur trim was a big deal for me based on personal experience but I ended up going with something without that. I made my decision on other criteria but the fur trim definitely weighed in. There is no doubt in my mind that fur or faux fur trim makes a difference. |

It absolutely has a function and it works. It keeps the wind off the face and retains some of the warm exhaled breath to warm the face and to mix with the fresh air being inhaled.
|
|
Certain species of fur, like wolf, work best because they do not trap moisture and freeze.
|
|
This is plainly obvious to anyone who has worn a proper parka in nasty weather, even before you factor in the filtering of blowing snow.

Thanks OP. Very interesting.
I have always felt warmer with the fur trimmed coat. Also, I swear my rabbit hat keeps me warmer than a face mask. I guess there is actual data to back this up!
|
|
Interesting, thanks for posting OP. I was just thinking about fur collars and effectiveness a few days ago, when remembering an old coat I used to have that had one.
|
|
So I can just wrap my Dachshund around my face when I'm out in the elements? Claymore is not going to be happy about this... |
|
I have long held the belief that in extreme weather conditions natural furs/ fibers and hide leather can out perform synthetics.
I have supplemented my cold weather gear with wool sweaters in the last few years and am still shocked how much better they are. Just a few weeks ago it dipped into the teens while working outside. All I had was a light under layer and a quality wool sweater and was just fine. Several friends had their heavy Carhart jackets and were cold. (I like my Carhatt jacket too) |
|
Yeah, it helps. (see state of posting), also differant furs have diffent properties. wolverine fur has some sort of texture that wont let frost build up on it so you wont get frosty vision on extended days. The mittens I use for extreme cold days have beaver pelt on the back, you can put it up against your face to keep it nice and toasty.

Thanks for the post OP. Interesting stuff.
I know hunters and trappers around here sell coyote pelts for this type of application. Is our local fur used domestically, or only overseas? |

View Quote A lot of fur is sold oversees because the prices they can get are higher. However what normally happens for most trappers is they sell their furs to a fur buyer. They prepare them by fleshing, stretching and drying them. Certain species are dried fur out and some are dried fur in. Fur handling is becoming a lost art for many areas. The big buyers then grade each fur and sell them in large auctions. The local trapper can easily send his furs in at the end of the season and then recieve a check. Fur has a big fluctuation in price based on quality and how well it was "put up" or prepared. I've seen $50 beaver skins reduced to $5 because of poor handling. Certain regions bring higher prices. Southern fur is inferior because our winters don't get that cold. While arctic regions may have some of the highest quality of fur in the world. You will also see a big difference in coloration and that can effect price too. I do commercial trapping and Unfortunately our state won't allow us to sell the hides for most of the year. But I do save some for personal use. ;-) |

Badass.
Off to Amazon to research fur lined jackets and hoods. |
|
|
I don't know what to say other than my extreme winter coat is a fur lined down parka.
|

Preach it brother!
(I have fur sitting up at NAFA and prices are not looking to be promising) Oh well, I lose less money trapping than any of my other hobbies! |

Homemade fur parka and outerwear is a hell of a lot better than any store bought.
Rabbit lined beaver hat and mittens are very very warm. Mukluks lined with rabbit and grass are the same. Rate the fur for ruffs this way Wolverine fur is hollow and will not ice up. Wolf comes a very close second. Also hoods on parkas are deep with a flap/ruff you can fold out for more protection. Wish i could afford a squirrel parka for everybody in the family. Bou are easy to get along with wolf/wolverine. |

View Quote You should get into nuisance trapping. Where people pay you to trap. It's the fastest growing division for us. I'm setting traps Monday in the shadow of 20 story high rise for coyotes. You don't even want to know what they are paying for two weeks of trapping. But I know fur trappers that won't make that amount all season. |

Great thread , old school tag . Its good to see the fur trapping guys chiming in , its something that always had my interest .

I was just wondering about this the other day. Excellent thread and article. I want a fur lined parka to go with some classic wool pants and sweaters. Does anyone make decent parkas with at least fur lined hoods these days?
|
|
Thanks for the pics. If you'll indulge a few questions, what's used for the lining and insulation? Are natural fibers used these days or have synthetics taken over? Are these made from patterns or from "experience"?

Other animal fur also works. People use both ways to make items. Ask away on anything. |

Commercial Parkas available that duplicate what the Inuit did???

My Father was in the Air Force and their winter coats had fur on the hoods.

At least around here, folks simply don't want to pay. Did get me access to some nice properties/hunting rights. Changing though, with more people moving into the area. MAy jump back in in a few years. |

Ever seen one of these I can't find one. It's not a far reach to see how the advantages of having for on the hood could also apply to having fur all over though. Also I am curious if artificial fur is as good or even close as real fur for this application. |

I have a memory that coyote fur when damp/wet smells like wet dog?? Some of the other furs don't have that problem.

Baxter State Parka is the name of the discontinued item. I picked up a barely used one (that actually fit me) at my local thrift for $20, but it lacked a hood. Contacted LLB via phone, gave them info from tags on the coat, and they sent me a new hood, right size and color, with attached (and removable) coyote fur ruff for free. Coat is olive drab/green, with Gore-Tex and has great quality down insulation. It replaced my vintage 1970 Eddie Bauer Kara Koram down parka, so I think that says something. |

Orvis Foul Weather Lined sweater. I got this back in November and have been wearing it a lot this winter. The windproof lining makes it usable as an outer layer over just a t-shirt and button down shirt down into the 30s. It's also a great mid layer. 2. Swiss military surplus half-zip pullover. This one is really thick so it traps a lot of insulating air in the loft. I've had it about a year and a half and been really happy with it. A friend of mine has an Irish fisherman's sweater that he wears in really cold weather. It has even more loft than the Swiss sweater, due to the cable knit pattern, which allows it to trap more air. The other nice thing about wool is that is doesn't get funky from B.O. the way synthetics do. It's even somewhat resistant to picking up the smell from a campfire. I wore my Swiss sweater at deer camp this year, with lots of exposure to smoke, and it doesn't stink. |

FWIW, here's my zero degree Fahrenheit go-to: http://www.backcountry.com/the-north-face-mcmurdo-parka-mens
Fake fur, though, and not quite as well insulated as some of the others. |
