  • O’Neill 3/2 Wetsuit - it’s an excellent choice for its intended use
Color: Black/Black Size: XX-Large
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. ... show more

  • 6’4 195 and LT fits like a glove
Color: Black/Black Size: Large Tall
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. ... show more

  • Least restricting wetsuit I have ever put on
Color: Black/Black Size: XX-Large
The 2mm stretch zones are as stretchy as any I have felt. Genuinely the least restricting full wetsuit I have ever owned. (This is my third) Nothing crazy, easy to get in and out of. Just a comfortable, wetsuit that is easy to paddle in for a fair price.

  • Good suit with just a couple minor notes
As comparison, I'm hard to fit, a bit musclebound but not super tall and the 'short' version of my size was very good. It's comfortable and you can move well enough. I know all neoprene creases but compared to my other wetsuits I'd almost say this actually wrinkles. Maybe it gets better with age. My particular unit also showed up with a huge zipper mark branded across the chest (ostensibly from a different suit's zipper, maybe in prior shipping). But I knew I'd be getting other creases, scrapes and scuffs in short order so I let all that go. The fit and range of motion was great and it kept me warm enough, which is what really matters. The other issue I have is the lanyard on the zipper is just like 6 inches too short. Maybe only 4. And it doesn't sound like a big deal until you're pulling a shoulder out of its socket trying to get it zipped up on a pitching boat deck. ... show more

  • Great wetsuit, perfect fit, poorly packaged by Amazon
Color: Black/Black Size: 3X-Large
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. ... show more

  • Cozy....
Color: Black/Black Size: 3X-Large
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 ... show more

  • Poor quality zipper.
Color: Black/Black Size: XX-Large
Zipper went all the way up without zipping up. With the suit on. When I took it off it was only zip on the left track and I only bought this last month. Poor quality and I don’t see any customer service. This repair is not cheap.
