Cleanline Staff Erik Says:“The Psycho Tech combines warmth and flexibility to a level that is unmatched. The updated Psycho Tech carries on with this legacy with all-new TechnoButter 4 and TechnoButter 4x for an even stretchier suit with the added strength of graphene to keep you warmer and in the water for longer. O’Neill has figured out the best way to keep the entry of the Psycho Tech comfortable and water-tight. The F.U.Z.E closure system is one of the best-designed entries on the market. The Psycho Tech is a great option for surfers in windy climates as the smooth skin panels on the chest, back, and hood help to cut windchill and keep you toasty warm.”

Additional Info
O'Neill uses recycled ocean oyster shells in place of calcium carbonate powder which comprises approximately 10% of their neoprene. O’Neill worked with their key manufacturing partner to develop a non-solvent based lamination glue called “aqua-alpha”. Aqua alpha reduces solvent usage by 600 grams per wetsuit compared to traditional laminating glues. Eliminates harmful VOCs and has the same durability as conventional, solvent-based Wetsuit glues. From recycled polybags to 100% recycled paper and soy based inks hang tags. Conserving water, energy and virgin materials. 100% digital catalogs. Dope-dying infusion produces colored yarns without the dyeing process. This saves tremendous amounts of water while reducing energy consumption and water pollution (up to 80%). 26% carbon emission is reduced for every kg of fabric. Every blueprint full suit saves more than 1 lb/0.5 kg of harmful plastic from potentially polluting the world’s living oceans. Carbon black is one of the key ingredients in neoprene. It can now be carbonized from scrap rubber tires using high heat to extract. 72% carbon emission declined. O’Neill’s advanced repair facility prolongs the life cycle of their product, keeping their wetsuit out of the landfill longer.
Product Construction
TB4 AIR FIREWALL
The next great thermal breakthrough was made better with trapped pockets of air. TB4 Air Firewall uses a special lamination process paired with a core of aerated neoprene and a graphene fiber jersey to create the toastiest conditions. Take summer with you.
TB4 FIREWALL
The all new Technobutter 4 Firewall utilizes the recycled graphene fibers at a thicker pile to create a fire hot feedback loop. As the body heat warms the graphene fibers they conduct the heat back into the body.
TECHNOBUTTER 4X
Technobutter 4x goes beyond the gooey stretch, and soft feel of TB3x. Recycled graphene fibers line the jersey allowing for incredible stretch with added strength and warmth retention, all with a new look.
TECHNOBUTTER 4
TB4 builds on the legendary Technobutter 3, the next evolution of the jersey introduces recycled yarns infused with graphene for increased wear strength and heat retention.
F.U.Z.E. ZIP CLOSURE
Front Upper Zip Entry (chest) uses a free floating zipper panel and anti flush barrier with drain holes to keep you dry and feeling loose.
STITCHLESS
Exterior Fluid Seam Weld and Interior TB3X Tape on either side of a stitch-less seam takes wetsuit construction to the next level. The all-new combination of reliable durability and low-profile comfort simply can’t be beat.
