O'Neill Reactor Wetsuits

O'Neill Reactor Wetsuit Range with chest and back zip, full wetsuit options available!

O'Neill, for many years, has produced the most cost-effective and quality range of performance and entry-level wetsuits for the whole family at a price that will not break the bank. The reason for this is the perfect blend between cost-effective pricing and the quality of neoprene used. The O'Neill Reactor series falls under the affordable, best value for money wetsuit bracket, and we guarantee that the features that come with this series at its price range make it an unbeatable offer. They are Flatlock wetsuits, meaning they are overlaid when the seams are stitched together. This minimises the water that can get into the suit through the seams, keeping you protected in the water. You can kit the whole family out and not spend a fortune; this also means you have wetsuits that you can use season after season. The Reactor wetsuits have also been built with some super stretch neoprene in the panels, so that when you are in the water and move, the suit moves with you rather than being rigid. Thus, not only do you get less tired, but you will also stay warmer for longer.

The summer O'Neill Reactor entry-level wetsuits are either 5/3mm full-length, 3mm full-length, 2 3/2mm back zip full wetsuits or 2mm shorty wetsuits, including the 2mm back zip full wetsuit, so you can choose how much warmth you need when you are in the water. They are designed for summer months in the UK & Europe, or even in warmer tropical climates if required. Built with durability and comfort in mind, this value-driven package ensures you can enjoy surfing, wakeboarding, sailing, and more with confidence. The Reactor 2 3/2mm back zip model is especially popular amongst surfers and kids, as it gives you the flexibility to match the temperature and conditions and change quickly.

With sizes ranging from XS to XL, O’Neill has made sure everyone is covered. The graphics, colour, and overall design have been carefully developed to meet the demands of the market while offering accessories to complete your kit. Every Reactor wetsuit is glued and stitched for strength, giving you long-lasting performance drop after drop. Many who buy and review these wetsuits agree that they represent the world’s number one choice in affordable wetsuit performance.

Built by O’Neill, backed by years of expertise, and trusted worldwide, the Reactor series is a package designed so you can enjoy the water season after season, no matter the weather!
