+1 for Waterproof. I have the W1 7mm and dive NE. Been down to about the mid-40º's with a 3mm core warmer and I'm absolutely fine. Front zip is nice but taking it off is best with a buddy. Well made. Also, I've heard that the W1 is discontinued (here in the states?). Also was told that the W1 and W2 use slightly different neoprene.
