O'Neill Reactor 2mm Spring Suit - 2017 Awesome Service, Good suit for priceReview by Rob Rob
Replacing a 15 year old O'Neill shorty. The wetsuit fits true to sizing charts and the fabric is much improved from old suit. Great wetsuit for the price. Thanks again for your quick shipping and friendly service.

O'Neill Reactor 2mm Spring Suit - 2017 Great service, great suitReview by smv smv
This is a great suit and the service was great. My only 2 minor complaints are that the suit was not as advertised in colors. For example the colors on the logo in front and on the sleeve were just plain grey, not as shown in the pictures ( Grey and blue) to match the overall color combination I bought. Also a bit expensive, $15 more, as I found the exact same suit in O'neill retail store at $75 and so is the online price at Oneill's web store as well... Other than that its great!

O'Neill Reactor 2mm Spring Suit - 2017 great wetsuitReview by mike hee mike hee
I am very satisfied with my new O'Neil Reactor spring wetsuit. I have been using O'Neil wetsuits for over 25 years and their quality is superb. I was also very satisfied with purchasing my wetsui from Cleanline surf. I live on Oahu and my wetsuit arrived on schedule and Josh and the crew aslo wrote me a little note about how lucky i was to live in Hawaii nice weather all year round. They also thanked me for purchasing my wetsuit from their shop. mike hee

O'Neill Reactor 2mm Spring Suit - 2017 Spend more for better qualityReview by Azel Azel
Worst wetsuit I have ever had. The wetsuit has put me off oneill. Rashes under both arm pits and crotch would ride up. The stitching under the armpit was dodgy which caused the problem. As for cleanline great service, I also bought a steamer which was great with quick postage and great prices
