Darwin or XLA fabrics

[JamesSwim]

Anyone have suits made with the Darwin or XLA fabric?

Some Barracuda suits are made with Darwin

and I have a Kiefer suit made with XLA.

They stretch like Lycra, but are different. Darwin is very soft, for example.

Are there other unusual suits out there that's not Nylon/Lycra
