They are designed to offer the support of a jockstrap with the benefit of added comfort and style. They are made from a tight fitting material and have a high leg opening. The fabric of the briefs covers the full rear seat area.  Briefs can come with or without a front fly opening. Originally available in only white, briegs were dubbed "tighty-whities" and were the standard in men's underwear up until the 1970s.

There is no fabric in the rear seat area. Jockstraps continue to see use in a variety of athletics with the wide waistband and leg elastic providing support to the genitals. For sports many jockstraps include a pocket for wearing a protective cup. Today jocks are worn as much for fashion as function and are available in a variety of styles and fabrics.

The two panels are connected on the sides by fabric and a waistband. Thong underwear is often called a "t-back" or "whale tail" due to its similar appearance to a whale's flukes.
