The Psycho One 4/3mm wetsuit is lightweight and loaded with all the features you need to make the most of each session. A team favourite here at Down the Line Surf Co..

The Materials:

  • Technobutter 3: An exterior jersey material that is highly stretchy, durable, soft and hydrophobic. The finest technical yarns are highly water resistant yet tough enough to withstand the heaviest surf sessions. Velcro resistant and soft feel to touch is just the icing on the cake.

  • Envy Neoprene: Microscopic air cells are held in the rubber core. Air is a fantastic insulator, so as these air cells warm up, this in turn warms the neoprene, making you a warmer and happier surfer. The air in the neoprene also makes it lighter by decreasing the mass. Unlike many other lightweight foams, Envy Neoprene retains its structure after repeated use.

  • TB3X: An interior jersey that is O'Neill's lightest and stretchiest ever. The TB3X is actually pre stretched to break the fibers to a point that they're flexed to the max, yet still hold their form. It's low profile also increases warmth by shedding water away from your skin.


  • Colour Way: FP5 - Graphite/Jet Camo

  • Z.E.N. Zip Closure - O'Neill's patented system with a free floating zipper panel and the anti-flush barrier-2 with drainage hole.

  • Fluid Seam Weld - 8mm silicone-based Urethane seal on the exterior of the seams.  Glued and blindstitched interior, make this a watertight, durable and highly flexible seam.

  • Minimal Seam Design - Increased flexibility thanks to the larger panels, specially designed and ergonomically cut to fit your paddling movement.

  • Krypto Knee Padz - Designed to extend the life of the wetsuit and protect the knee while duck-diving, the Krypto knee pad is made from an abrasion reistant high stretch neo panel

  • Double Seal Collar

  • Anti Flush Barrier

  • 100% Technobutter 3
