Men’s underwear, on the other hand, whether they are briefs or boxers, shorts or trunks, athletic supporters or jock straps have always been primarily functional in that they conform to the contours of the male body, and are made with sturdy and protective fabrics.
The oldest example of men’s underwear, the loincloth, dates back to the cave man. We know this because in 1991 a leather loincloth was discovered in the Alps along with the remains of Otzi, the iceman, who lived around 3300 B.C. Scientists discovered that Otzi wore a leather loincloth under his woven grass cloak.
