A friend of mine recently bought the new (and legal) top of the line Jaked and I must say I was quite impressed with the material, which supposedly contains polyurethane. It feels very sturdy and thick, much like the old LZR. He hasn't swum with it yet though.
I think before anyone races in a suit they should only wear FINA approved suits. Here is another list of the suits. Is the suit you are going to get approved. www.fina.org/.../index.php
So I just completed the purchase of the J01full body. I got it in Red. THe total cost was 117 Euros (not sure where the discount came from). I assume i will never be able to wear it at a meet, but it will be fun to practice in.
