O'Neill Psycho Tech Wetsuit

The 5/4mm thickness is built for frigid, cold-water conditions, typically ranging from 45°F to 55°F (7°C to 13°C). It is specifically engineered for winter surfing or extended sessions in near-freezing water.

The F.U.Z.E. chest zip offers significantly better flexibility and warmth compared to a back zip. By eliminating the long zipper down the back, the suit moves more naturally with your spine and creates a tighter seal that prevents cold water flushing.

Yes, the Fluid Seam Weld technology is highly durable. Because it eliminates needle holes, it prevents water entry while reinforcing the seams, which actually helps the suit last longer than traditional stitched seams that can fray or leak over time.

Since this is a 5/4mm suit designed for cold water, the integrated hood is essential for heat retention. It prevents the rapid body heat loss that occurs through your head and neck, allowing you to stay in the water for much longer sessions.

These features are designed to create a watertight seal at your wrists and ankles. They grip the skin tightly to prevent water from rushing up your sleeves or legs during wipeouts, keeping your core temperature stable.

O'Neill uses recycled oyster shells and eco-carbon black infused into the neoprene. These materials reduce the reliance on petroleum-based products while maintaining the high-performance stretch and thermal retention required for cold-water surfing.
