O’Neill Mens Hyperfreak 4/3mm Fuze Zip Steamer Wetsuit is part of O’Neill’s continuing range of high-performance wetsuits. The Hyperfreak series is one of the most flexible types of surfing wetsuits we’ve ever laid our hands on. The insanely stretchy TB3-X Neoprene offers the greatest elasticity of any technical neoprene thanks to the Envy Foam core rubber which effectively insulates by maximising cell volume without increasing the chance of cell-wall failure (cell wall failure basically turns your wetsuit from foam into a sponge). Wetsuit ‘rubber’ is actually a closed-cell foam but you can get the rundown on our Neoprene Blog.
The Hyperfreak range of O’Neill Wetsuits is their highest performing range of wetsuits and in true O’Neill, fashion has pushed performance where no one else has gone before. In the age of ‘green’ wetsuits, it’s easy to get bogged down in misinformation but one thing we know for sure is every dollar spent on the O’Neill Mens Hyperfreak 4/3mm Fuze Zip Steamer Wetsuit results in the utmost performance.
We’d recommend a 4/3mm thickness wetsuit for winter conditions anywhere South of Sydney, however, you might opt for a 3/2 if you’re going to be in Northern NSW or South-East Queensland. This all depends on personal preference.
To get the most out of your wetsuit we recommend washing it with Wetsuit Wash & reading our maintenance guide.
O’Neill Mens Hyperfreak 4/3mm Fuze Zip Steamer Wetsuit Features:
- TBX-3 Neoprene: Arguably the stretchiest neoprene available, we’ve felt a lot of wetsuits over the years but nothing has felt as supple as the TBX-3, so much so that we audibly gasped when inspecting it… Did you know that the ‘rubber’ inside a wet suit is actually foam? It’s important to remember that the stretch factor is not dependent on a single aspect of the suit but on the combination of the core foam, the linings and the seams – O’neill tout 220% combined elasticity without permanent deformation. Get learned at our Neoprene Blog.
- Glued & Blind-Stitched Seams: GBS seams use a hooked needle to ensure no pin-holes are made during the sewing stages, as a result, the only passage for water is the gap between the two panels but O’Neill plugs the entire suit with an elastic glue that not only stops all water flow but barely affects the overall stretch of the suit. It’s not the most expensive but it’s certainly one of the best seams around. Intrigued? Check out our wetsuit seams vlog.
- TB3X Fully Taped Seams: Taped seams reinforce the GBS stitching to prevent tearing and their water sealing capabilities. TB3X taping is super flexible too – so it won’t hinder your flexible technobutter neoprene.
- Chest Zip Entry: A no-brainer for any performance wetsuit as it’s warmer and dryer but drastically increases the entire suit’s stretch factor. Read our exposé vlog on wetsuit entry systems.
- Double Super Seal Collar: Two layers of neoprene in smooth-skin neoprene lining creates an effective seal against the skin around the fully adjustable collar.
- Strategic Seam Placement
- Aqua Alpha Solvent Free Lamination
- Drainage Holes
