Here is an article that quantifies the heat loss effects of cotton, polyester and polypropylene: Rossi et al., Dry and Wet Heat Transfer Through Clothing Dependent on the Clothing Properties Under Cold Conditions, International Journal of Occupational Safety and Ergonomics (JOSE) 2008, Vol. 14, No. 1, 69–76. Experimental Summary Here is a rough summary ...

They are basically measures for the quality of the down fill. The 90/10 part refers to the mixture of down and feathers. As down contains nearly no rigid structure, one adds some amount of feathers to give the whole filling some more stability. The example of 90/10 means 90% down, 10% feathers and seems to be quite a typical mixture. I'm not sure about the ...

Yes, there have been studies on how much various fabrics insulate when wet and dry. I remember Dr Murray Hamlet mentioning these statistics in one of his lectures on outdoor survival in the cold. It's been a long time, but I think cotton looses something like 80% of its insulating properties when wet. I may be off on the exact number, but I definitely ...

Make a big fire. This may sound silly and couterintuitive, but the reason is pretty simple. If you make a small fire you need to put your stuff pretty close to it to have any chance of drying it in a decent amount of time. And if you put clothes or boots near the fire, then you concretely risk to burn them. While if you make a bigger fire, your equipment ...

Black robes are worn predominantely by Bedouin tribesmen. A scientific paper has been written on this Why do Bedouins wear black robes in hot deserts? article in journal Nature. This is summarised quite neatly here. To cut a long story short: "It seems likely," the scientists wrote, "that the present inhabitants of the Sinai, the Bedouins, would have ...

Some general rules: layer system also for the hands is a good idea but those gardening gloves won't work pretty well better use inner liner gloves (wool or even a softshell glove) and a warm mitten as the outer layer to avoid cooling off use hats (again use a layer-system) including a warm winter hat which covers the ears (also see this about heat loss ...

Its not necessarily bad as long as you are careful, also somewhat dependent on material. Generally, you want to arrange your clothes so that they are about a temperature where you could comfortably hold your hand. If your clothes are steaming keep a close eye on them and think about moving them back. Material is also an important factor synthetic ...

The variety used by pipe fitters working the oil fields in the Great White North: You sound like you're working on the oil rigs, which explains why the pointer finger on your gloves keeps blowing out. Ski gloves and climbing gloves aren't going to take the abuse of turning pipe all day, what you need is a sturdy pair of leather gloves with a reinforced ...

If the suggestions in Everything's answer don't work, try these heating options: Heated gloves (I have linked to an example) Hand warmer packs to tuck into your gloves My wife has Reynaud's which leads to poor circulation in fingers and toes, so needs to use these solutions on occasion, and they are very effective.

There is this informal study that suggests there isn't much difference between wet gear of any fabric. http://woodtrekker.blogspot.com/2012/11/cotton-vs-wool-insulation.html But it misses the point entirely. It's not getting wet that kills, it's how long it takes you to get dry afterwards that kills. A much better test would be to keep the water at a ...

Down is the lightest and most compressible delivering the best warmth. Down is the undercoating of water fowl. It provides the greatest amount of dead air space of any insulation material for its weight. A down pod consists of light, fluffy filaments that grow from one quill or point. These filaments intertwine and mesh, forming air pockets which trap air. ...

Ticks can attach anywhere, in particular, they will find spots like the back of your knee, around waistbands, under armpits, undergarment straps or any other constricted place. Firstly, prefer to wear the clothing which is already treated for tick prevention by means of some tick repellent solution. The solution is supposed to contain Permethrin. Spray ...

While reading the answers to this question I had to disagree at some points. For example referring to @DavidR I don't think that Softshells are generally less windproof than Hardshells. Over the last years it seems that the manufacturers are mainly producing Softshell with Gore-Tex Windstopper membrane. I wouldn't say that those jackets are really that good, ...

Goretex, generally consists of three chemicals. The outer The outer (wear resistant part) is simply nylon or polyester. This is typically non-hazardous and can be disposed as any other plastic (bearing in mind the long periods of time this is likely going to take to decompose) The inner This is the "Gore-tex layer". Goretex itself is simply a ...

This depends on the actual type of clothing and mostly on the wind speed. The wind evaporates moisture from the body. Since evaporation is a cooling process and absorbs latent heat away from the body, the person feels colder. Skin always has moisture on it. Just like a tree transpires, the human body is constantly having water evaporated from it. Wind ...

Could the use of anti-perspirant give benefit in extreme cold climate where sweating can be a significant problem. TL;DR answer: Unlikely. The issue is the sheer amount of water your body will secrete during physical exercise. It would be impossible for anti persperant to prevent this amount of moisture. To clarify Anti-perspirants work by: ...

When to use it: An vapour barrier is used when the temperature is very cold and when a wet down-suit/sleeping bag, clothes or shoes can cause serious hypothermia. It's also used if you can't dry your stuff because of no sun, cold temperature or bad weather, so everything stays dry at least from the inside. Thinking behind this: When the isolation layers get ...

When you are facing a serious sweating problem, maybe your overall setup is too warm. What layers/jackets do you wear above the one-suite-fleece? I am thinking of a very thin layer which is highly breathable and will just be a shelter against the elements (wind, rain/snow) like e.g. the Gore Active Shell. Still, sweating to some degree is pretty normal. ...

Not Cotton Related: Does cotton really kill? Any active base layer will suffice as long as it is not cotton. Cotton is great for keeping you cool, but terrible for wicking moisture and keeping you warm. The classic "Union Suit" that your suit is modelled after was developed as, and is still worn by some as underwear, so you could use your suit as your ...

I have friends who swear by silk inners. They are thin, so can be worn under other gloves, but are extremely warm for the thickness. Combine these with windstopper outers - as mentioned elsewhere, layering is good practice. On the downside, silk is really expensive, at least where I live. On the upside, silk lasts a long time and doesn't get smelly.

I'm pretty sure this concept originated with search and rescue teams, who noticed a correlation between what the lost hiker was wearing, and whether the result of the search was a 'rescue' or a 'recovery'. I strongly believe this to be true, and I tried to find good data online, but no luck yet. If somebody can find a proper, double-blinded study of the ...

As always the answer differs depending on application, the experimental summary above tells us what happens very well while offering a conclusion that is only subjectively useful. In my own experience cotton is comfortable, inexpensive and can be obtained in the right size, but should not be used exclusively when traveling outdoors any significant distance ...

http://www.gore-tex.com.au/faq/w1/i1085252/ How should I dispose of a GORE-TEX® product in an environmentally safe way? Garments or footwear made from Gore laminates can be safely disposed of just like any other apparel product. Contrary to most other plastics, Polytetrafluoroethylene (PTFE) – the raw material of our membrane - is not made or ...

One problem with hemp compared to wool is how it conducts heat when it is wet. Wet hemp conducts heat very well when wet which means your feet could get freezing cold. Wet wool is a poor heat conductor so even if wet they will not be as cold.

I think your basis for this question is a bit out of skew with the myself more at risk clause. The difference between truly top end Merino Wool and lesser quality wool is the micron (µm) being used. The really good quality stuff, say, Icebreaker, uses the highest quality micron which results in a warmer garment that is able to handle ‘peripheral temperature ...

Although I agree with AM_Hawk as down being both light and compressible, I'd also suggest layering your clothing. Trapping heat between layers keeps warm air near your body, even without using a specific material. The first layer is packed tight next to your body and regulates moisture / sweat: It keeps you dry. For example, a tight t-shirt. Next, a layer ...

When I was in central Alaska, courtesy of Uncle Sam, we wore vapor barrier boots. They are great for extremely low temperatures, but of you are heavily exerting in milder weather* (down to -23C/-10F range), your socks would get downright soggy. Some soldiers did put anti-perspirant on their feet to help with cold and trench foot symptoms. If plastic ...

The UK company Rab have a reputation for selling jackets and tops with longish sleeves. I'm 6'3" (I don't know about 'wingspan') and find quite a lot of their jackets/tops have sleeves more than long enough for me, perhaps a bit too long in some cases! Also, here is a link to Rab's sizing guide, which also gives sleeve lengths: sizing guide

I think it's good to wear long clothes and close all small entry spots through the layers. You can also use some repellents that contain 20 to 30% DEET (N, N-diethyl-m-toluamide) for your skin and permethrin for your clothes. But for hunting and also if you're doing some sport or work it's normal that you can't protect yourself 100% from tick bites. I ...

From looking at the pictures I would say that for the "default" conditions at summer glacier/alpine tours they should be perfectly fine. In dry but slightly coldish conditions they will give you good grip and rope handling, as long as you don't have to dig through snow with them. The reason why you have got cold fingers while cycling might be on the one ...
