Since no one else has answered: I am going to guess "no." I say that because I have three of Waterproof's same/similar suits but just the previous generation (and I don't detect a major neoprene change). I have the 3mm, 5mm, and 7mm versions.
These are not super-stretchy neoprene. I won't say they are "rigid," but I have tried on the hyper-stretchy suits and these are not like that. I believe the Waterproof neoprene is less compressible though, which probably gives it better insulative performance.
Also, the suits are cut with quite a few panels, which "shapes" them (so the suit is more tailored to fit rather than stretchy to fit, if that makes sense). Also, they come in a very large variety of sizes (again, to fit via shape).
I love both of my Waterproof suits and find them to be very well made and with some nice features. That said, if you are looking for super-stretchy, you might be disappointed.
