O’Neill Wetsuits Reactor II 3/2mm Full Suit Review

If you are looking for a full suit at a great price this O’Neill Men’s Reactor II 3/2mm Back Zip Full Wetsuit checks most of the boxes on your ‘wish list’. It has some great features normally found on more expensive models.

  • The shoulders and sleeves are made from a super stretch neoprene fabric that allows full, unrestricted upper body movement. All the Reactor series of wetsuits have this feature that O’Neill has branded ‘FluidFlex’. The ergonomically designed under sleeve panels are seamless, allowing you greater freedom of movement without chafing.
  • The smooth skin chest panel is a nice feature and the zipper is strong and sturdy as you would expect from O’Neill – this suit features a full-length snag-free YKK back zipper.
  • The seams are durable, with smooth flatlock stitching. Flatlock construction with breathable overlocking flat-stitched seams is ideal for use in warmer conditions, is very durable and hard wearing and provides chafe-free comfort.
  • This suit has Krypto knee pads. These ergonomically shaped high stretch and abrasion resistant neoprene panels protect your knees and protect the suit from damage too. The paddle zones are seamless ensuring maximum comfort and freedom of movement.
  • A single, super seal neck which is designed to avoid bulk in a fully adjustable closure with a smooth skin chafe-free finish all the way around the inside of the neck and edge. This neck styling effectively resists flushing.
  • There is a handy key pocket inside the garment.

All O’Neill suits are supplied with a 12-month warranty covering both materials and craftsmanship but your suit will give you several seasons of great service with a little care and maintenance – especially rinsing in fresh water immediately after each use and hanging to dry on an appropriate hanger.
