Egalian wim pants have the particularity to have a long fly , which goes down until the crotch. This enables wim to pee standing, without having to take their pants off. This long opening used to be present on menwim’s underwear as well, from the middle age to the 17th and 18th century, allowing menwim to relieve themselves without taking off their many complicated clothes. This particularity disappeared from the male wardrobe when the garments became more simple, and therefore easier to take on and off. Nowadays, most of menwim pants have a really small fly, just enough to be able to put on the pants, or sometimes no fly at all when the fabric is stretchy.
