This doesn't leak like my other, warm with nice cuffs and neck. Fitment is true to size with their chart. I had a short large and needed an short xl.

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.

I’m 5’8” 190 lbs., with 46” barrel chest and wide shoulders and back, 30” inseam, and this suit fits perfectly in XL Short. I have a very hard time finding non-custom wetsuits that fit, so I’m thrilled about this one. Usually when I find a one piece that fits up top, the legs are about 6” longer than I need. I plan on using it for temperate water Scuba. Due to my wide lats I can only get the rear zipper up half way by myself due to material bunching, but the fit is not restricting at all once fully zipped with some help.

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.

Love my wetsuit! Had to figure out the best size, but I got it right and it’s so comfortable. I wore it kiteboarding and it never felt bulky.

Purchaded in large im 5ft 10 180lb sleeves sre a tad long and the legs a tad but fits everything else well. I have the LS size but its just a bit small. Tore just under the zipper so large is solid Especially my chest shoulders back. Worn it my last 5 session. So far I love it! I love how it feels and stretches, it's a bit tight around the groin. The back zipper does fall down abput an inch doesnt let water in when it does this just have to sometimes pull it back up every so often.. is annoying but I also have a fairly wide back to cause this. Water drains good and keeps me warm. In North Florida so the water doesn't get to cold. But cold enough. I'd purchase again or recommend to a friend.
