The popularity of the Australian Speedo brand racing brief has led to the use of its name to refer to any racing brief, regardless of the maker. Swim briefs are also referred to as competition briefs, bathers, racer bathers, posing briefs, and racing briefs.

Like underwear briefs, swim briefs feature a "V-shape" front and a solid back providing form-fitting coverage. They are usually worn below the lower waist, but some of them can be worn at the waist (resembling the briefs worn by some professional wrestlers). They are generally secured by thin banding at the upper thighs and either a drawstring around the waist or an elasticized waistband.

Here's a small tribute featuring the Speedo and the men who wear them. Enjoy.
