Dolphin shorts or Dolfins are a specific style of unisex shorts worn for athletics.
Dolphin shorts are a style of unisex shorts designed to be worn for athletics. They are typically very short and were originally made from nylon with contrasting binding, side slits, and rounded corners, with a waistband at the top—a style popular in the 1980s.[1][2]
The name is from Dolfin, the American company that first produced this style of shorts in the 1980s.[2]
