A lot depends on the climate, on your budget, and on how much you sweat on the move. Pros and cons of merino Merino is the king if you want to prevent odour and most people find that it's the most pleasant against the skin. It wicks quite well but holds around 25% more water than synthetics and takes around 50% longer to dry. Another issue is abrasion - if ...

There is a difference between just soaking up water and "wicking". Cotton is hydrophilic, which means it likes to attract and hang on to water molecules. Unlike a good wicking fabric (which relies on capillary action), cotton will not transfer that water up through your layers to the air as quickly. Here are some reasons why a wet base layer is bad: ...

Cotton doesn't wick away any moisture, it will soak and capture it. Furthermore cotton is heavy (compared to other materials), doesn't insulate, becomes wet very quickly, and stays wet for a long time.

A lot of the cooling effect of sweat comes from evaporation so it is debatable whether wicking vs non wicking is better in hot dry conditions. Having said that in very hot and low humidity environments it may be a moot point. One area where it may make a difference is if you are wearing a large pack, in this case sweat can build up under the straps and ...

The odors probable came from your shirt clinging on to all the perspiration, and not having a chance to dry out. If you can afford the weight of a spare (or sleeping) shirt, spring for it so your wet clothes can dry overnight. It also helps to coordinate the rest of your clothing. If you're sweating, make sure anything you're wearing over your baselayer ...

The advantage of layering is that it is versatile so for example if you have a base layer an insulating layer and a shell layer you can wear only the base layer in hot weather, base layer plus shell layer in mild but wet weather, base layer plus mid layer in cold dry weather or all of the above in extreme weather. Soft shell jackets and lofted down or ...

You must consider here why you would be sweating in the first place. So, you must take into account that the body may produce a bit more heat from time to time and it will want to dump that excess heat into the environment using evaporative cooling. E.g.in Northern Norway I had to travel a bit to get to a place where I could take pictures, when I arrived I ...

Another disadvantage of cotton is that, because it holds on to moisture and gets saturated quickly it can get very uncomfortable where it is between your skin and your pack, especially around the straps and back. Over a long day this can get quite unpleasant and over a few days you can get serious skin problems from salty sweat being rubbed against your ...

If you carry the right layers and adjust them well, you can often get away with cotton with no discomfort let alone danger in benign conditions. But we shouldn't plan for only benign conditions and nothing going wrong. An example:If you're delayed and the weather changes for the worse, you could end up with cotton under waterproof layers just as the ...
