Abstract: An athletic supporter is provided having in combination as elements of construction a waistband, leg straps and a genital-supporting pouch. At least the waistband and the pouch of the supporter consist essentially of a knitted or woven fabric of elasticized polypropylene fiber which in the form of a fabric has a coefficient of stretch in all directions of at least about 50% per linear inch and a recovery to the unstretched state in excess of about 95%. The polypropylene fabric, which preferably contains spandex, is characterized by a substantial degree of moisture transfer, with the fibers thereof substantially non-absorbent to moisture, the polypropylene fiber having a specific gravity of approximately 0.9.
