That article contains some silly statements.
Neoprene is a synthetic rubber. Only when it is used in a foamed form does it provide flotation. Neoprene used in wetsuits is foam. Whatever substance is used in the B70 is not foamed. It is a coating over lycra or lycra-like fabric.
I happen to believe the B70 DOES provide a small amount of flotation - but not because the suit itself floats. I think the suit's rubber coating traps a small amount of air in the lycra fabric. I think the LZR has a similar property - but the LZR doesn't coat all of the fabric - just specific sections.
(I have a B70 and used it for the first time two weeks ago)
