Oh come on, Lycra while a brand name is used interchangeably in common language for the material that most synthetic bike shorts are made from as many do contain some percentage (usually small) of Lycra(TM) fibre and if not Lycra then some similar perhaps non-branded stretchy synthetic fibre - spandex. These fibers are not made from rubber.

I am also quite sure that Lycra containing products do not say "wear in open air to help moisture absorption" That would be stupid. And any material in open air will have greater moisture loss whether or not it has Lycra in it.
