The one that started our love affair with crazies: the O'Neill Psycho 1 Zen-Zip 3/2MM FSW Wetsuit. Streamlined and redesigned for 2010, the Psycho 1 3/2 Fullsuit features Fluid Seam Welds, Z.E.N. Zip closure, Plasma seals, an external key pocket, double-lined UltraFlex DS neoprene, ultra-minimal seaming, and Firewall insulation on the chest and back for added warmth.
