Japanese Suits

It seems like Japanese material wetsuits are all the rage these days. Gato Heroi is making them, Capt. Fin Company is making the Sea Vessel, Nine Plus has been around, Almond is coming out with a new line, and so on. So i picked up a Joel Tudor/Amsterdam top for $50, I have yet to take it for a test drive, but from trying it on, it feels more flexible than any other top i've had. Japanese material wetsuits are known to be warmer, stretchier than American suits, but are a little more fragile. Will report back on results.
