ONeill O’Neill Mens Psycho Tech 3/2mm Chest Zip Steamer Wetsuit

The O’Neill Men’s Psycho Tech Chest Zip Steamer Wetsuit 3/2mm is a top-of-the-range surfing wetsuit featuring completely sealed seams, Fuze chest zip and the extremely supple and flexible neoprene and jerseys that O’Neill has become so well renowned for. It’s a shame you, the internet shopper, are unable to have a feel of this wettie given how ridiculously soft and stretchy the TB4 rubber is.

O’Neill achieves this stretch in the Psychotech 3/2mm by increasing the gas content within the rubber layer of the wetsuit; it’s this gas content (typically nitrogen) that gives the neoprene its high stretch factor (the rubber in a wetsuit is actually a closed-cell foam, learn more about neoprene on our blog about wetsuit differences).  It’s a less known fact that the trapped gas inside the middle layer actually makes the suit warmer! To complement this flexibility the seams are welded instead of stitched, with stretchy TBX-4 internal taping, which gives increased flexibility compared to traditional stitched seams.

We reckon the O’Neill Mens Psychotech 3/2mm Chest Zip Steamer is suitable for winter across most of Australia’s east coast – in QLD we would consider this to be on the warm side, but it’d be an ideal thickness around Sydney. Further south and in Victoria, you might opt for a 4/3 (at least), but it all depends on personal preference.

To get the most out of your O’Neill Men’s Psycho Tech Chest Zip Steamer Wetsuit 3/2mm we recommend washing it with the Australian-made Wetsuit Wash and reading our Wetsuit Maintenance Guide.  

O’Neill Men’s Psycho Tech Chest Zip Steamer Wetsuit 3/2mm Features:

• Thickness: 3/2mm 
• TechnoButter 4: This builds on O’Neill’s legendary TB3 material. The TB4 jersey is next level introducing recycled yarns infused with graphene for increased wear strength and heat distribution. 
• TB4 Air Firewall: using a special lamination process paired with a core of aerated neoprene and a graphene fibre jersey to keep you incredibly toastie. It increases thermal retention by trapping tiny air bubbles in the fibre-weave, an idea borrowed from sea mammals like seals.
• Chest Zip: Learn more with our seams blog. 
• Fluid-Weld Seams: O’Neill has been a strong proponent of removing all stitching from a wetsuit as it’s one of the least stretchy components.  They achieve strength and durability, without stitching, but by triple-glueing the panels together. Of course, this is completely sealed against water but the no-stitching equates to more stretch! Learn more about seams with our blog. 
• TBX-4 Internal Taping: This stretchy internal taping is meant to reinforce not just the strength of the welded seams, but also their water sealing.
• Krypto Knee Padz: long-lasting durability without impacting comfort
• Key Pocket
• Super Seal Cuffs
