This wetsuit is brilliant.  O''neill really "gets" it when it comes to neoprene.  The stretch is truly amazing (especially for a 4/3) and the warmth has kept me surfing much longer in water that is usually in the lower 50''s.  Actually the suit may be too warm, but better too warm than too cold when it comes to water sports. Zero flushing by the way...

Here''s my gripe.  I spoke with a guy that works at O''neill and he was raving about the Z.E.N zip.  I have always favored front zips.  Well, as expected, I got the rear zip on this suit snagged on the inner lining of the wetsuit and had to actually go home to get it off.  Real bummer.  I know it''s user error on my part but a heads up as to what could happen when you''re not paying attention would be appreciated.  The zipper snagged 2 inches of neoprene and it took some strength and finesse to back out the zipper.  Anyway...buy this suit if you like back zips.  If not, find a front zip like O''neill''s RG8 series.
