The human body already has a highly efficient cooling system: As perspiration evaporates, it draws heat away from the body. Wicking fabrics facilitate this process by distributing sweat evenly over the fabric, so that it dries more quickly. Despite devising cheats, such as menthol-like chemical coatings added to fabrics, companies have never actually improved upon the body's natural cooling process. Designers at Columbia Sportswear have now made a fabric that does.
