They are Christmas gifts. We brought 2 suits. One for our 6?Äô guy. Large tall. Fit perfect. One for our short heavier guy 5?Äô7?Äù xlarge regular another perfect fit. Said they wore them twice behind the boat and love them. It just extended their winter months on the water. They love knee boarding and ski. Thank you! The 3rd suit I had to find on Amazon as you didn?Äôt have another large tall ready available for Christmas holiday and they wanted to be out in the water.

I tried a lot of different brands and found that nothing would really fit as I needed it to, being 63, 253lbs and way out of my normal 210lbs weight bracket. I tried in O'Niell the Epic, Excel's Axis which fit perfectly but too expensive for something I will soon not be needing as I lose weight.The Epic was good but for some reason, as with most of O'Niells the last 15 yrs, they are 2 - 3 inches too short in the legs. The 2XL Fit perfectly but was way too short in the legs. The 2XLL was the same exact length in the legs (2 inches above the ankle) and instead added several inches in torso length and arm length. Now I'm not some disportinate man at 6'3 and 210 - 220 (normally). I'm now 253 because of an injury but still the same problem I've had with O'Niell for a ... MoreI tried a lot of different brands and found that nothing would really fit as I needed it to, being 63, 253lbs and way out of my normal 210lbs weight bracket.

I'm now 253 because of an injury but still the same problem I've had with O'Niell for a long time still seems to plague my favorite company and go to wetsuit throughout the 80' and 90's. It was so precise back then that I never needed to try on suits from one year to the next because I never changed height or weight and was an XL all the time. Then one yr they cut the leg length and it has still been the same issue almost 20yrs later.Luckily this wetsuit fit me perfectly and despite being just a touch short in the legs, it was nowhere near as short as the Epic. I don't know maybe I'm just tripping out and after 42 yrs of surfing I just forget how to correctly get into a suit.But despite all the issues I had with the Epic and every suit across the line up for a long long time now. This one is almost perfect. At $124, almost perfect is actually good enough for me.I do wish that whoever is involved in the design department would take a good hard look at what these suits are doing for men of my height who have a really normal athletic build, broad shoulders and look like an athlete. Add an extra 1 1/2 inches in the legs on your regular sized XL suits and XXL suits and stop adding so much torso length and arm length in Long design. You guys are really missing the mark here and I wish it was the same go to brand I've always relied on growing up.Great job on the Reactor 2 though, I'm super stoked.

I've worn O'Neill wetsuits for 40 years. I've purchased the last 3 or 4 online without trying them on depending on the perfect fit of the XL size. I'm an athletic, not fat, muscular, middle-aged guy, 6'1" 205 pounds, 34 inch waist. This XL suit is comfortable, easy to get in and out of and warm enough for chilly air and cool water. It would not be suitable for cold conditions, air or water. Most of this suit is nylon on the outside allowing the evaporation cooling effect, not desirable for cold air conditions in wind sports. If I had it to do over, I might spring for a smooth skin suit and I'd try it on first. Back to fit: This suit is looser in the legs than all other XL O'Neill wetsuits I have owned. It will work, but will not go on my "good wetsuits" list.

Five stars for a reason; check it out.

This is my first wetsuit and it was a great choice, perfect for swimming and bodysurfing in Northern California waters, including SF Bay. I have pretty good tolerance for 60 degree water, the wet suit eliminates the shock factor (especially on the upper body) and makes for a more enjoyable experience. Very comfortable/easy for open water swimming.One learning: make sure the zipper is all the way to the top and the velcro flap engaged, otherwise you will take on more water than you care to as you swim.I'm 5'7, 150, with a 32" waist. The size MS fit perfectly; the size chart was right on. Service was terrific; I received my shipment on the West Coast just a couple of days after ordering.Looking forward to wearing it out!

Great suit and customer service to go with it.
7 June 2023

I was replacing the same suit that I had for 25 years that finally gave up. If this new suit lasts as long as the first one, it will outlive me. Love the product.I had a problem with the first suit I received, a torn stitch. WW sent a replacement with zero problems.This company stands behind what it sells, and I couldn't be happier.

Great suit, top of legs a bit wide
4 October 2022

I received the suit and tried it in my sit on top canoe with 17 degrees Celcius outside temperature and it was really warm. The breast piece was a good shield against the cold wind and the arms had enough stretch and room for a good paddle movement. The only thing is that the upper legs were a bit wide for my not so muscular legs, so the suit is a bit floppy there. And i would appreciate a small piece of ribbon or neoprene at the down end of the zipper to be able to hold the bottom of the zip with one hand while pulling it up with the long ribbon with the other hand. In that way there is less stress on the zipper. This could be a product improvement i think.! Otherwise great!

KNOW WHAT YOU ARE GETTING
25 July 2022

The description is incomplete and O'Neill customer service does not know the details of this suit. I called, they told me the entire outside of the suit is "smooth skin" and the neck edge is finished with trim. I ordered one based on this information. The suit is in fact mostly "nylon 2" neoprene, meaning there is nylon on the skin side and outside, not all "smooth skin". Only the chest and back are smooth skin neoprene or what used to be called "Nylon 1". The neck has an unfinished edge with smooth skin on the inside and nylon on the outside, no trim. The fit is amazing. But I'm sending it back and will purchase a smooth skin suit for wind sports.

Questionable mid sizes
18 December 2022

Have several Oneils wetsuit.I Left my 3/2? behind recently so needed an inexpensive replacement while away.Being 5?7? and very skinny in the legs and wrists, found medium to nearly fit right but not perfect, lose in some spots . Chart size didn?t quite match reality.Although not O?Neil?s fault the store had limited sizes with my normal size not quite as snug as I would like, I just tried on whatever size seemed right when held up to my body. Ended up with size 19? I don?t know if that?s children or women?s? But it fit nice on legs, ankles , wrists and hight, but very tight across shoulders, upper arms and neck.I bought it, but I was very restricted in it and tired easily because it wasn?t as stretchy and flexible as I was hoping with a newer suit.

I got a little cold and shivers after about an hour, (normally last longer) probably part to do with being a little-restrictive and I lost heat through energy loss, (because the water was 20c (70f) )which isn?t too cold., so it could?ve been partly I got the wrong size, or it?s partly that it?s flat stitched but not sealed and leaks minimal along stitching areas, or both,I?m not sure.I normally like Oneil?s for price and fit, but when shopping by labels for sizes, perhaps they could make clearer labeling sizes with and make more in between sizes like other companies.But overall I still recommend.

Sticking with O'Neill
21 January 2023

Bought this on the basis that my Reactor II 2mm Springsuit has been, and is, an excellent wetsuit. I haven't had occasion to use the steamer yet, but I expect it'll be every bit as good or better. The only weakness in the springsuit is the collar, which is deteriorating faster than the rest of the wetsuit, but at this price point, that is, to me, quite acceptable. All the same, I'm hoping the weakness has been addressed in this newer steamer. Also, my online purchase experience was extremely good.

Stoked!
22 October 2022

I have been wearing ONeill wetsuits since the early 1970s. Love them. This Reactor 2 Spring Suit is the best spring suit I have ever worn. Soft on the skin, stretchy, comfortable. Perfect for early sessions in 70 degree water and 60 degree air. And also happy to have found Wetsuit Wearhouse! Good price, fast free ship, and really good return policy. Thanks! I'm still stoked at age 75!
