O'Neill Hyperfreak 4/3+mm Men's Chest Wetsuit in Navy Now it's not often we really praise a new wetsuit, but the new Technobutter 3 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's 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. Being a 4/3+mm this is a great all-year-round wetsuit for those that are in the UK waters from April till December. 4.5mm wetsuits are becoming more and more popular every year due to the extended use you can get out of your wetsuit.   FEATURES   Thickness is 4.5mm on the body and 3.5mm on the arms. Technobutter 3 Neoprene is the lightest and most flexible neoprene on the market.
