Men's Reactor-2 3:2mm Back Zip Full Wetsuit, Lightweight Warmth and Flexibility for All Water Activities

I’ve 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 O’Neill 3/2mm “entry-level” wetsuit is a solid choice when you need a bit more than a rash guard but don’t want the bulk or don’t need the warmth of a full 3mm suit. It’s perfect for those in-between water temperatures—where a swimsuit is too little, but a full 3mm feels like overkill. The flexibility and comfort are impressive for an entry-level option; it’s easy to get on and off, and I’ve found it moves well in the water without feeling restrictive. It doesn’t provide the full insulation you’d want for colder dives, but it’s 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 O’Neill 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 doesn’t come with some of the sealing features you’d see in mid- to higher-end suits, so if you’re 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.

Great wetsuit. fits just right. Awesome price and awesome quality. And looks great!

I’m new and haven’t 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 I’m comfortable it will perform well in the water. I’ll. 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.

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.

The fit is perfect. The leash to zip it up is the perfect length. The cuffs at the sleeves and ankles feel like very little water if any will come in. I could already feel my body heat retention not leaving the suit so again I feel confident I won't be shivering at 25 and 30 ft depths. I will update again after my first freedive in a few weeks at Lake Ouachita at Blakely Mountain Dam. Last year's wetsuit was a Dark Lightning 3 mm and I floated like a cork. If you were snorkeling, I guess that would be a good thing as you wouldn't have to work so hard to stay on top of the water. But the drawback was two things. First, water came in at the sleeves and the ankles which I tried to avoid and yes it was cold. When you are a freediver, you want to stay warm, but you DON'T want to work yourself to death trying to swim down 15 or 20 ft. The Dark Lightning suit wore me out because when I got to the bottom of the lake, I didn't have any air left to enjoy the dive because I kicked so hard to keep from floating back up to the top. The reviews on the O'Neill state the suit is not very buoyant which will also be a big plus if indeed that is the case. Also, hopefully this year I will be making the trip to Beaver Lake to their dive park there and reviews already state the water there is much colder than most lakes in Arkansas, but much to see. Promise to update review after first successful excursion with my new O'Neill wetsuit. Just as a guide for the fit, I am 5'11 and 170 lbs. and I ordered the common M size with the perfect outcome for the fit.

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.

I'm 6'3" and have trouble finding a wetsuit long enough for me - until now... This fit perfectly. Long enough for both my arms and legs and didn't fit like a tent around me. Highly recommended for tall, slender men.

Excellent
