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.

5.0 out of 5 stars Great wetsuit, perfect fit, poorly packaged by Amazon
Reviewed in the United States on January 26, 2023
Size: 3X-LargeColor: Black/BlackPattern Name: Full WetsuitVerified Purchase
Amazon did a terrible job shipping this item. It likely has permanent creases from being bunched up in a bag. So, be warned, it's likely that you'll have similar issues; I suspect that warehouse associates don't know much about properly folding and shipping wetsuits. That said, this is a great wetsuit and a great value. It's very well made, comfortable, and a perfect fit.

I'm a 6’1 Male, 248lbs, with relatively wide hips, which can make sizing a chore. I got the 3XL (based on their sizing guide) and it's a perfect fit. Definitely recommend the wetsuit, but I haven't decided if I should try and get a replacement that hasn't been aesthetically damaged.

I'm 6'2"/250lbs. This thing fits great. It's tight around my belly, but who's fault is that. I'll be losing 20lbs before getting this or my boards wet. This thing has really nice flexibility. Very agile and easy. I went out in 40 degree weather, and it was a little cool, but you could definitely tell it was the goods. I kind of didn't want to take it off. It's like getting a hug.....everywhere :P

5.0 out of 5 stars Fits well, and works well for rated temps
Reviewed in the United States on June 5, 2021
Size: XX-LargeColor: Black/BlackPattern Name: Full WetsuitVerified Purchase
Here in the Bay Area, the ocean gets all the way up to 55F in the peak of summer so... I like to have. wetsuit for beach days so I can spend more than a few minutes in the water. This is a great suit for that purpose. Easy to get into and out of too.

Depending your local water temps, I think it'd be a good suit for surfing too. There are always new materials coming out that are marketed as "more stretchy", "less restrictive", etc... for surfing but I think the materials have improved so much across the board in the past couple decades that the difference between a modestly priced suite like this one and the more expensive "super flexible" suits is becoming pretty insignificant.

I received this Oneil wetsuit today and it just about fits me perfectly. I am 6'2 waist 41.5" chest 49.5" neck 19.5" arm 23" inseam 34". While putting on I did feel like my wife putting on skinny jeans bouncing around to get my legs in the suit. The neck is a little snug. I haven't been in the water yet, but I feel the brand will live up to its name. Will revise review once I've tested the suit. Stay Tuned.

I surf once or twice a week and think this is a great middle of the road wetsuit. The more expensive suits so block out the water completely. This suit slowly leaks water but that's okay because the thin layer of water warms to your body temp and so it is fine. I expect it to last 2 winters. Time will tell.

The size isba perfect fit, and it looks decent too. I got somewhat of a belly so I was a bit worried how it would look wearing spandex but it didn’t show much. Quality was superb too, it was warm, the material was sturdy, zipper was smooth. No complains

I have purchased many wetsuits in my life. This wetsuit is beautiful, great quality and great fit. I am 6ft tall and wiegh 211lbs and purchased an XXXL. For some reason sizes seem to be getting smaller, hence the triple large need but that seems an overall trend and is not O'Neill's fault. I will continue to buy thicker suits from O'Neill for colder water forays.
The suit even has a 'silky' feel versus rubbery so to speak...
Thanks O'Niell!
