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 ...

Your legs aren't as sensitive to temperture extremes. Right now it's winter here and I'm walking around outside with a regular shirt, a wool sweater, and a wind breaker on my torso. Inside I take off the windbreaker an sweater. However, inside or outside, I'm wearing the same single-layer pants and it's not a problem. My legs don't feel hot inside or ...

Yes it is possible to sunburn through clothing. Clothing does block some of the Ultraviloet radiation but not 100%. A lot of outdoor recreation clothing is now marketed with treatments that gives additional UV protection.

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 ...

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 ...

Although black clothing absorbs radiation from the sun more than white clothing, this is somewhat offset by the fact that it also emits it more efficiently. Good absorbers are also good emitters. If you're standing in dark shade and the objects in your environment are cooler than the temperature of your clothing, then black clothing will theoretically cause ...

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 ...

There's a reason desert cultures almost all wear coverings from head to toe. Three main things to consider: Protection from the sun's harmful rays. Air flow for convection cooling Moisture retention (you heard that right) for evaporative cooling. Despite the convention, "cotton kills," in the desert those same properties (slow drying, water retention) ...

To be honest I was dubious about getting something that I thought was gimmicky, but my son’s Scout troop was selling custom Buffs to raise group funds so I ended up buying one. A Buff is just a tube of lightweight, stretchy material. I’ve found them useful in three particular situations: They are thin, so can be worn like a hat under a bicycle helmet for ...

Don't use cotton socks for hiking. When your feet sweat, the socks become wet, and take forever to dry out. Good socks remove the bacteria and moisture that thrive in the environment created by sweating feet and help to prevent blisters. Cotton retains moisture, thus cotton socks will not do the job properly. Rather, buy non-itching ("merino") wool, ...

I'm not sure why pants don't receive the same attention but the layers are available. You can easily find base, insulating, and shell layers. Olin's answer gives some good reasons layering pants may not seem as common. In reply: (2) There are full-side-zip pants for mountaineers (crampons) and wide-opening pants for skiers/boarders and regular boots. ...

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 ...

The short answer is, it varies. The three factors that most influence the UV transmission factor of clothing are kind of obvious: Material: Some materials are better at absorbing UV than others; for example, the paper cited below suggests that polyester absorbs more UV light (particularly UVB) than cotton. Weave: The thicker and more tightly woven a piece ...

I strongly recommend you purchase, borrow, or possibly rent a proper ski jacket and pants. Given that you don't have a ski jacket I'm guessing that you are a relative beginner. It is likely that you might be falling down quite a bit. One thing to consider is does your jacket give you good mobility? If it does not, you could very easily expose your waist ...

Nylon, among other synthetics, is an ideal material for clothing for most outdoor pursuits for several reasons. I will use the example of cotton as the traditional fabric for comparison: Durability: Nylon itself can come in several varieties, some of which are more durable than others due to different weights and weaves. The fabric can handle abrasion, ...

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 ...

Sleeping with the socks on your torso is the most effective method I have found, and it does not require anything you wouldn't already have. For this, you just: Take socks off Put them inside your shirt, under all layers of clothing. They must be touching your skin. Sleep Wake up in the morning with dry socks. This works with a lot of things: socks, ...

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 ...

When washing rain coats and fleeces I use Nikwax tech wash and reproofer (millets link), on the bottle these say reconmended for Goretex so I assume it's the same. In general with waterproof clothing do not use normal washing powders as these remove the waterproof coating.

Correct size. That might sound obvious, but consider also width and height (of the instep). Each make is a bit different, so there's a need to try on many before you find one that fits really good. For all-day trips get boots one size larger than your usual office shoes are. Vibram sole If properly maintained, leather upper is much more waterproof and ...

The liner acts as a climate control mechanism for your body through a reduction of moisture and an increase in circulation. The synthetic fiber content acts as a wick to pull the moisture away from your skin, while the mesh composition acts as a suspension system that increases airflow by maintaining separation between your skin/undershirt and the remainder ...

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 ...

My experience in this field is quite limited, but this is what I'd look for: Light - Hiking boots should be as light as possible. Believe me when I say that walking around when carrying a ton sucks. A proper sole - and by proper I mean one that isn't too hard or too soft. Too hard will provide little to no traction on slippery surfaces, and one that is too ...

I have always been advised to be in bright/light colours during the trekking expeds in regions which are known for bad sun. Everybody knows that Black clothing absorbs more heat(radiation). The lighter you wear, the lesser heat you attract(radiation). Now there is a point rightly said above that the darker colours will emit it faster as well, but the ...

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 ...

The wikipedia article on sun protective clothing is very informative. A summary of the relevant parts: Apart from clothing specifically marketed as protecting against the sun most clothing will not block all sun to fully protect you against sunburn depending on circumstances. Some general rules of thumb: Darker clothes provide more protection than ...

a two layer winter hat to protect your ears a good winter jacket (long enough) supporting -40ºC (-40ºF) winter boots a two layer gloves a scarf For the intermediate layer: The key point is to not sweat. Depending on your body, you should choose the appropriate "heat level" intermediate layer. Some shops will have different categories from very cool to ...

According to one study of one species of mosquito, "attractiveness was found to vary inversely with their reflectivity or brightness, although the different textures represented in the series tended to obscure the generalised relationship" (Brown 1954). Meaning the brighter the clothing, the less attractive for one species of mosquito found in Canada... I ...

All Gore-Tex products come with care instruction, these should be followed, obviously. It's important to understand how these membranes work, I feel. Many Gore-tex and similar products consist of 3 layers, the first layer (inside the jacket) is designed to protect the Gore tex fabric. The second layer is the actual Gore tex itself The outer layer ...
