Talk about cream of the crop. Built for moderate to colder surfing conditions, the O'Neill Men's Psychofreak FUZE 43 Wetsuit combines the high performing Psychofreak series with the beloved Psycho 3, takes it for a wild roller coaster ride, and then gives it a loop de loop finish with the incredibly effective FUZE entry system. This limited edition wetsuit is crafted with the most lightweight and effective firewall technology O'Neill has ever created the unique TechnoButter 2 Air Insulation and the quick drying TechnoButter Neoprene, in turn laying it on thick at 43mm. The TechnoButter provides ample warmth, optimal body temperature regulation, and moisture wicking while the FUZE entry system which happens to use the same zipper technology as O'Neill's patented ZEN zipper closure keeps you dry without restricting mobility. Thanks to the super seal cuffs, double super seal neck gasket, and double super seam welding technology you get watertight, stitchless technology so no water can sneak its way through and bludgeon your session like an angry troll. The Krypto Knee Padz and strategic seamless paddle zones encourage a fine tuned, comfortable fit and uninhibited range of motion. And the external key pocket with loop ensures safe keeping of your shiny valuables, so you can worry less about that spare getting lost to Poseidon and focus more on the waves that are headed straight toward you.
