Polyester/Lycra vs. Nylon/Lycra

[SwimTeamSpeedo]

The Nylon suits of the past were really all Nylon. Lycra was not around until the the 70's, thanks to our friends at Dupont, who created it. Before the Nylon suits, suits were made of wool... I think Speedo started putting lycra in their suits sometime in the middle to late 70's, could have even been early 1980's. Poly lycra has gone out of favor becasue poly has about the same wear strength as lycra, and is more stretchy, so the suits did not hold up well.
