Cotton doesn't really breath. "Breathing" is something that the cotton marketers want you to imagine it does. The truth is that cotton holds on to moisture, which then prevents what little ventilation the cotton ever had from happening. Cotton prevents natural processes from happening and then your body has to work extra-hard to compensate for it. If your cotton clothes had a respiratory system, they would need a scuba tank to keep from drowning when you wore them.
Don't know where you got that from. I have been doing needlework for nearly 30 years, so I am very familiar with the properties of fibers. Also, I live in an area that sees temperatures of 115 degrees Fahrenheit in the summer, so it is to my advantage to know which fibers breathe and which don't. Cotton breathes, and here is the Wikipedia article to back me up.

I can't see how cotton can be even remotely considered as something that breathes.
