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 ...

Having built several fires while wearing down jackets I can confirm that your jacket will not burst into flames, nylon is not that flammable. The worst you will experience is a small burn hole in the outside if an ember lands on you. Probably still a good idea to keep a safe distance away anyway there are plenty of other ways to burn yourself on a fire. Me ...

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 ...

I have a high-end gore-tex jacket and my wife has Paramo. I also have Paramo trousers. They are quite different: Gore-Tex is designed to be a physical barrier that prevents water getting through, while Nikwax Analogy (the fabric in Paramo jackets) is designed to be highly water-repellent and wick water quickly from inside to out rather than being actually ...

In the context of camping, it's perfectly safe to wear a down jacket. Keep in mind that fleece is typically also made from synthetics, and so can be expected to have similar properties to your down jacket. (Actually somewhat worse, given the texture.) A table of synthetic fiber characteristics at ...

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 ...

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 ...

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 ...

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.

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. ...

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. ...

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 ...

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: ...

Your question is also addressed at http://www.outdoorgearlab.com/Down-Jacket-Reviews/buying-advice High-end jackets often use lighter-weight fabrics and high-quality down. The only practical differences between them may be in features (hood? two-way zipper? water bottle pocket?) and exact fill weights. Lower-end models may use heavier, more durable ...

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 ...

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 ...

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 ...

It may be safe for you, but not for your jacket. While it won't instantly burst into flames, your very expensive jacket will get holes melted in it by hanging around a fire, same goes for any other nylons or non fire-resistant synthetic materials. Goose down will burn fairly well, oddly enough there are quite a few youtube videos of people burning down ...

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 ...

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.

Hold up two pieces of cloth in front of the sun, one black and one white, and see for yourself which passes more light. Dark cloth can be very thin and still block light effectively. Re-emission of energy from darker colors may be a little faster but I think other factors (see below) are much more significant. And don't kid yourself into thinking people ...

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 ...

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 ...

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 ...
