O'Neill have produced for many years the most cost effective and quality range of suits for all the family at a price that will not break the bank. They are a Flatlock suit that means when the seams are stitched together they are overlaid. This is to minimise the amount of water that can get in to the suit through the seams. The reason they are O'Neill's best selling wetsuit is because of the cost effective price and quality of neoprene used. 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. They also benefit from having 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 ridge. Thus not only do you get less tired you will also stay warmer for longer. The Reactor wetsuits are either 3mm full length suits or 2mm shorty 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 the warmer tropical climates if so required. Being multi purpose water sports suit you can use them no matter which sport you are into, so keen surfers, wake boarders or those sailing will love the feeling of the Reactor.
