LEVYSA TECHNICAL FABRICS:
It is a form of polyester microfiber (often blended with elastane/spandex) that is light in weight and engineered to wick moisture away from the body and move it from the skin to the outer side of the garment where it can evaporate and help the wearer keep his or her body temperature lower. Unlike cotton, which is hydrophilic and soaks up perspiration until it is thoroughly wet, Dry-FIT doesn’t hold the moisture any longer than it takes to move it to the outer surface of the garment.
In very humid or rainy conditions, therefore, it’s possible that Dry-FIT would not perform much better than a lightweight cotton. But in other conditions, especially when the air is not oppressively humid, and/or when there is relative air movement (created either by breeze or by the movement of the wearer), Dry-FIT will keep most wearers drier and more comfortable during athletic exertion.
