A true waterman knows that the O'Neill PsychoFreak 3.5/2.5MM FSW Wetsuit is the cream of the crop for all their surf needs. The ultimate in neoprene: XDS-Air, is double lined in the Psycho Freak, keeping you warmer than any standard 3 mil fullsuit has kept you before, and fewer seams and large expanses of un-broken panels mean the ultimate in flexibility. Throw in a double superseal neck, plasma seals, D-Tox knee pads, and 2X Fluid Seam Welds, and you've got proof positive that the O'Neill PsychoFreak 3.5/2.5MM Wetsuit is the suit that God himself would wear if he surfed...and he does...
