Product Description

The 2009 O'Neill Psycho II wetsuit... The Psycho II got a new model number this year and you O'Neill Wetsuit fans know what that means!  The new features you've been hearing about are here.  The Ultraflex XDS Neoprene is the softest, stretchiest wetsuit material in existence!  It stretches 125% - think about that, that's just an insane amount of stretch for a wetsuit. 

The new entry system for the Psycho II is amazing.  When I heard about it, I wasn't too impressed, but seeing or rather trying on, is believing!  The pullover crew neck gasket thingy... that's revolutionary!  This is why O'Neill wetsuits are the best wetsuits on the planet! 

The new Psycho 2 is on the loose. Thanks to new innovations in UltraFlex XDS neoprene technology the Psycho 2 is warmer, lighter and more flexible than ever before. Add in our Firewall (X-type) with gummy X-foam, and new ergonomic D-tox Knee padz and you can be confident you'll have the most insane suit in the water.
