O'Neill Mens Hyperfreak 4/3mm+ Chest Zip Steamer 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 stretch factor is not dependant on a single aspect of the suit but the combination of the core foam, the linings and the seams - O'neill tout 220% combined elasticity without permanent deformation.

• 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 plug 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 .
• 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 .
• Uninterrupted Torso Panels: Wetsuit stretch is a % function. That is to say: if a neoprene has 200% stretch then 1m can stretch to 2.2m without permanent deformation. If you chuck a seam in the middle of that panel, it won't stretch to 2.2m because seams don't stretch as much as neoprene. Therefore, by removing almost all the seams from your front and back means the greatest possible stretch!
• 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: O'Neill has minimised the total number of seams on the Hyperfreak Fuze springsuit which in turn creates a more flexible suit. The same notion as the uninterrupted torso panels!
• Aqua Alpha Solvent Free Lamination
• Drainage Holes
