Soccer Girls With The Football Ball Wearing A White Sportswear On The Lawn

Sportswear design must consider the thermal insulation needs of the wearer. In hot situations, sportswear should allow the wearer to stay cool; while in cold situations, sportswear should help the wearer to stay warm.
Sportswear should also be able to transfer sweat away from the skin, using, for example, moisture transferring fabric. Spandex is a popular material used as base layers to soak up sweat. For example, in activities such as skiing and mountain climbing this is achieved by using layering: moisture transferring materials are worn next to the skin, followed by an insulating layer, and wind and then water resistant shell garments.
