O'Neill Hyperfreak 4/3+mm Mens Chest Zip Wetsuit in Black
The O'Neill Hyperfreak 4/3+mm chest zip wetsuit for Men is a new suit for 2025 and has been upgraded to now include fully taped seams to ensure no water intake whilst maintaining flexibility. The + relates to an extra 0.5mm of Technobutter 3 neoprene on the body of the suit and an extra 0.5mm of 3X neoprene on the arms and shoulder giving you additional warmth and still maintaining incredible flexibility. This a brilliant suit for those wanting to be in the water from April until January if you are looking for one all-year-round suit.
Now it's not often we really praise a new wetsuit, but the new Technobutter 3 & 3X neoprene is absolutely amazing. Weirdly, it feels like an item of clothing to the touch and is the most flexible neoprene we have ever seen. When it is on it truly is the most comfortable suit we have ever tried and it's not just about how it feels as the technology gone into this suit is mind-blowing. The neoprene is pre-stretched so you will not lose shape over time and it is just the lightest, most flexible and soft material ever created by O'Neill.
Technobutter 3 is simply the best neoprene we have ever encountered and in the inner part of the suit, you will see the lines designed to drain any water from the suit whilst you are in the water. This wetsuit is going to be a game changer in terms of future suits and how much you will be enjoying your water sport.
