Perfect for Cornwall
This is the first wetsuit I've purchased ever, I was nervous about the purchase about getting the wrong size or type. But purchasing this has been no regrets so far. I got this for sea water swimming and also body boarding. I moved to the South East coast of Cornwall. After a few swims in the sea since the start of summer and still being a bit chilly I decided to get a wetsuit. I opted for a 2/3mm wetsuit reluctantly due to the prices. However, it is more than sufficient for the water currently at about 14.5°c. The wetsuit made a massive difference to my body temperature and I found I could complete a lot more swimming, I only got out due to being tired rather than being cold. The quality is really good. I opted for the O'Neill brand as I much prefer labels. O'Neill doesn't disappoint in this case. With regards to the fit, it was pretty much bang on. I'm six foot, around 14 stone with a bit of a belly. I tend to find I need extra room in the crotch department with most clothing, and this being tight in its nature did present a slight issue but not enough to cause off putting discomfort. It looks really good quality too. I expect it will be long lasting given the correct care. The stitching is very good. The zipper is easy to grasp and you can put it on alone. In terms of wearing it, I found I could swim normally. No strokes were inhibited. Overall, I'm glad I got this!

Brilliant wetsuit
I'm fat. In other wetsuits I've had the opportunity to squeeze into, they've always been too tight in all the places that a body needs to function. This is an excellent wetsuit. Loose enough to let the blood move within me and tight enough to not make me look like the big fat fatty that I am. I use it for paddleboarding and it doesn't chafe or rub anywhere. Really easy to get in and out, the back zip is ace and the lanyard on it is really sturdy and long enough that you don't dislocate a shoulder zipping it up. I do float like a black Michelin Man though which is pleasant.

Very comfortable and warm - perfect for swimming
As size is so important, here are my details - 6ft2, 87Kg and 34" waist. I bought size XL and I use it for open water swimming and triathlon. Sea temp I used it in is about 15 degrees. I've not used it for other water sports. I picked up this wetsuit for a great price and it arrived promptly. It's easy to get into and, importantly for triathlon, out of. The fit is slightly lose around the shoulders and it flaps a bit on the upper arm after swimming for 10mins, but it's not too bad and I can adjust it easily enough mid-swim. I'm not sure if a L would be a better option. It appears wells made and there are no visable defects. Most importantly, it warms up after a few strokes and is extremely comfortable for swimming. No hesitation in recommending.

Nice adult suit
Nice flexible 3mm suit - good for summer in Cornwall. Really flexible and easy on/off. Only gripe is it's so flexible that when waves hit me while I was taking a board out then it pushed the wrist of the suit up my arm - wasn't really an issue and I like the suit. I got a 3XL and I'm 6'3" and a bit overweight but it was a good fit. Perhaps if I got a smaller size the wrists would be a bit tighter - I dunno.

Great wetsuit at a great price
I thought there must be a catch to get an O'Neill wetsuit for this price, but its arrived and I've tried it on and it is excellent. So it seems like it is just a great deal! The neoprene is softer than my previous wetsuit and the rubber on the chest area is going to be better for wind protection and gripping the board. It also looks cooler! For sizing, I am 92kg and 182cm tall and the XL fits me perfectly.

Bought XL size, delighted with it
First wetsuit ever purchased, wasnt sure if was going to fit. Followed the chart supplied and its fine. I'm 6 foot and weigh 14 stone, 42 inch chest and 34 waste. I didn't want suit stuck to me and clinging to my body restricting movement. My waist is 34 in trousers but took the size 35-37 waste on chart to allow a bit for my belly. Yes OK I carry all my excess weight on my belly. I'm working on that. Didn't want 34" suit as would literally cut circulation off. The material is flexible thank god. It arrived today only 3 days after ordering even though order said 1-3 weeks. Tried it on and fitted comfortably without feeling like a grape in a press. I went for XL size and glad I did. Still to try out on my new paddle board I got. Waiting on lifevest first. Delighted with purchase. Holds my belly in a bit and I'm sure in time look flatter.

Basic wetsuit. Not sure the price is worth it re quality, compared to cheaper brands.
Surfed using this 3:2 wetsuit for a long time now. A basic wetsuit that seems no different than cheaper entry level suits. Honesty cant tell why this one would be £40 plus more than alternatives. The stretch is good, it's comfortable although they really need an XLT version for the taller surfer as the legs come up short on me and I dont want to compromise the fit. Wearability seems good, although the cuffs constantly roll / flip back in surf, which is annoying. Not had this on other wetsuits and the fit is perfect on my arms and exactly the same as others i own. Everyone differs regarding warmth and only you will know how cold you get in certain situations. Sometimes i need to use a thermal rash vest underneath this in the late spring / summer, sometimes not. ***Just clarify, this is not a winter or cold weather suit*** If you're a new UK surfer or someone that feels cold more than others you can go for a 4:3 suit for the summer and 5:2 ish for winter. However, i prefer to be a little loose in the legs, so I opt for a 2mm thermal rash vest under a 3:2 when its a little chillier. Overall though, the suit does the job and with the exception of the cuffs and leg length options, its ok as an entry level suit. For the increase in price though over a Gul for example, I would consider either spending more on a better wetsuit, or getting a cheaper branded suit that will do exactly the same thing.

Sin duda es un neopreno que se ajusta perfectamente . Cumple con su funcion, la calidad es óptima y satisface totalmente mis necesidades. En cuanto a las tallas también ha sido muy fácil interpretarlo dando que las opciones eran amplias y ha cumplido con su cometido . El servicio super rápido y el empaquetado igual. Es totalmente recomendable

O'Neill è una garanzia. Ottima muta che mi calza a pennello, oltre all'ottimo prezzo competitivo. In giro si trovano mute di marche sconosciute più cara. Quindi prodotto stra consigliato. Info riguardo la taglia se può essere d'aiuto: Sono 183 cm per 77 Kg. Ho preso una L ed è perfetta.

- schnelle Lieferung, unbeschädigte Verpackung, Ware wie angegeben - sehr gut! Der Anzug ist aus sehr elastischem Neopren, am Körper 3mm, an Armen und Beinen 2mm. Das An- und Ausziehen ist sehr einfach und auch bei vier Tauchgängen am Tag nicht nervig. Ich bin 1,80 Meter groß und wiege 90kg. Sportlich bedingt habe ich einen eher ausgeprägten Oberkörper und weniger an Bauch und Hüften, weshalb mir normale Größen oft nicht gut passen. Dieser Anzug passt sich allerdings, aufgrund des elastischen Neoprens, sehr gut an meine Figur an. Wärmeisolierung beim Tauchen ist ok, was man halt von 2/3mm erwarten kann. Vier +60-Minuten Tauchgänge in 28-30C° warmen Wasser sind kein Problem. Verarbeitung des Materials und der Nähte ist auch gut, nichts wirkt billig oder qualitativ minderwertig. Einzig der „O'Neill“-Schriftzug löst sich etwas ab aber das ist nicht so relevant für mich. Die ersten 40 Tauchgänge hat der Anzug gut gemeistert und auch eine erste 30-C° Maschinenwäsche hat er überstanden. Hätte ich geahnt, dass der Anzug so gut ist, hätte ich den schon vor zwei Jahren gekauft, anstatt mich noch in meinen alten, steifen, zu engen 3-er zu zwängen.
