I've done a little bit of research about this, but the sites I found explain it in a too vague manner (and with absolutely no pictures at all), so my knowledge is really patched. There are many questions in my mind right now.
Could you give a detailed explanation of moisture-wicking with pictures or videos (ELI5 style), or at least point me to that source?
If wicking is based on capillary action, then putting decency aside, is playing naked still better than any kind of Spandex? You know, maximum surface area in that case, while sportwear will never be fully attached to difficult areas like the armpits.
in activities such as skiing and mountain climbing this is achieved by using layering: moisture transferring (wicking) materials are worn next to the skin, followed by an insulating layer, and then wind and water resistant shell garments.
Does that mean the sportwear will become a balloon full of water? Because water will be trapped between the transferring material and the insulating layer, with no moving air to help the evaporation because of the resistant shell, LOL. This significant extra weight is a climber's nightmare IMHO.
- Still Wiki:
Drywicking is the newest variation of moisture wicking. It is a smart two tier fabric that breaks the surface tension of sweat and propels it through the hydrophobic layer into a natural wicking outer layer
How can a fabric break sweat's surface tension? What does it have to do with the easier propelling?
That's about all I can think of for now. Thank you.
