excellent wetsuit
This is a very good and comfortable wetsuit, I appreciate the fact it keeps me warm even in cold temperature , while not affecting the mobility doing watersports. Review carefully the size as it's size a little bit small.

6ā4 195 and LT fits like a glove
Iām new and havenāt put it to the test yet. at my height and weight, finding a suit was a bit of a chore. This felt very good, it was more flexible than others I tried and great quality. It fit from head to ankles and was the right torso length. It is incredibly warm so Iām comfortable it will perform well in the water. Iāll. Try and put out an update when I test it. Update, I did a few dives at 70deg and was relatively comfortable. The third dive I was feeling the cold. I naturally get cold easily.

Looking forward to comfortable, warm surf sessions with this suit this coming fall and winter.
Just a note on my credibility and expertise....I have longboard surfed Socal for the past 55 years and gone through dozens of wetsuits of most major brands. I am easy to please but hard to fit. I just received my O'Neill 3/2 Reactor 2 today and found the materials to be very good quality and well put together. I was a bit reluctant to order an O'Neill based on many years ago past experience of O'Neills being seemingly built for tall, slender individuals (of which I am neither,) but I couldn't pass up at this price (1/3 the cost of my current fullsuit) an opportunity to give O'Neill another chance for my future business. I am 5-10/210 lbs with a beer-barrel 45" chest and 36" waist, kinda like a '50s wrestler. I ordered an XL suit based on the sizing chart, and past experience of XLS being too restrictive. The good news is that with the new super-stretch materials the suit pulled on and off no problema. (OK Wetsox helped a bit and I highly recommend them.) It was properly snug without feeling binding, and the neck, wrists and ankles feel very watertight. It was not baggy in the arms and legs. It looks like it's gonna work fine. The bad news is (1) that the neck was pretty tight on my 18" neck, and may become uncomfortable over time; and (2) I couldn't get the zipper started up without the help of my laughing wife. (I've always thought wetsuits should come with a tab at the base of the spine to hold on to while pulling up the zipper. I often have one put on by a local suit repair.) As the water temps here drop next month I'll give the suit the 'acid test' with a few surf sessions. I'll update this review if any discrepancies are found, and how it performs.

OāNeill 3/2 Wetsuit - itās an excellent choice for its intended use
Iāve had this wetsuit for 2 years and I use it for when scuba diving. I have approximately 20 dives in it, so my review is in that context. As seen in the posted pictures, it is still in near-new-like condition The OāNeill 3/2mm āentry-levelā wetsuit is a solid choice when you need a bit more than a rash guard but donāt want the bulk or donāt need the warmth of a full 3mm suit. Itās perfect for those in-between water temperaturesāwhere a swimsuit is too little, but a full 3mm feels like overkill. The flexibility and comfort are impressive for an entry-level option; itās easy to get on and off, and Iāve found it moves well in the water without feeling restrictive. It doesnāt provide the full insulation youād want for colder dives, but itās great for milder conditions. I used to dive with a 3mm shorty wetsuit when in Cozumel and that was OK 90% of the time. I now find the OāNeill 3/2 is a better choice on boat dives, especially on that chilly boat ride back to the dock after the second tank dive My only minor gripe, and it is a minor one, this model doesnāt come with some of the sealing features youād see in mid- to higher-end suits, so if youāre in water with a mild chill, you might feel it around the seams. For the price, this is a very capable wetsuit that keeps the chill off, balancing warmth, flexibility, and ease of use. Definitely recommend for anyone looking for a reliable wetsuit in warm to mid-temp conditions, especially so considering the price and the quality of this item.

Good fit and value.
I was looking for an entry level wetsuit to water ski occasionally. Was unsure about size but finally went for a Large-Tall. It fits perfectly. For context I'm 6'1 (185cm) and 180 lb (82 kg) with a lean muscular fit. Was a bit worried it would be too long or to loose around the waist -happily that is not the case. I read in some reviews that ppl tend to go for wetsuits larger than needed. I also tried the MT and L (that friends have). The MT was a bit tighter but also fit well... I'm trying to put on some extra muscle mass which is why I went for the LT -If that's not a concern and you like a tighter fit then go for the MT. The L had shorter sleeves/legs but was also a good fit. At that point it really came down to the LT being on sale.

I've had all three price range wetsuits from these guys, the $300 one, the $500 one, and now this really cheap one. For the money I say this is a good suit. It lets a little bit more water in than the more expensive ones, and the fit is just the tiniest bit loose around the thighs and lower back. I'm 5'10" and a medium build for reference. I love the back zip models for ease of getting in and out. I think in future I would probably go back to the $300 version for a better fit. All in all very good though

zipper broke off first pull. Only had a 2 week window and delivery was help at a depot only open for an hour in morning and 2 hours in afternoon approximately. Shocking but what a waste of money. And no response from company either
