You literally quoting a piece of commercial copyrighting (=ad) to contradict knowledge by experience. It's not like one data point, cotton is highly unpopular in hiking, and athlete communities. 1. Because it's strongly hydrophilic it absorbs water, and keeps it. 2. It's sorta breatheable while it's dry, but not so much when wet, and see p.1. 3. I guess you can find a type of cloth which dries worse than cotton, but plenty of synthetics do it better anyway
