  • It's a little tight, but that's how it should be

  • Great fit, great performance, one minor annoyance
Color: Black/Black/Black Size: XX-Large
XXL was perfect for 230lbs/6ft tall with a big belly/chest. I've never had a 4/3, but have decades of experience using thiner wetsuits and neoprene gear for different activities. Most of my stuff is around 2mm. It's crazy how warm 4mm is - I used this suit in 50-55F water and I couldn't even tell I was in the water. Only flaw with the product is the neck velcro easily gets stuck inside the suit and is very difficult to get un-stuck once the suit is on. I know what you're thinking: "they all do that." Not like this; the velcro absolutely welds itself deep inside your shoulder, even if you try to be careful about not dragging the flap in. This annoyance is worth it for the price; still a great value. No fault of the product, but the suit was sent in a box that was literally 6ft long, 3 inches deep, and around 30 inches across. This is obviously absurd, and might be a consideration depending on where you are sending the suit. Also, the suit had clearly been tried on and returned, which is a little gross, but fine with me. ... show more

  • Fit & Usage
Color: Black/Black/Black Size: Large
Fit is true to size chart. I'm 6'3" 210 and suit fits very well. Bout this about 3-4 weeks ago. I have used this suit at least 15x now for work in temps ranging from 68° - 76° for multiple hours each time with no complaints. Warm with very little flushing. Zipper area you'll get some coolness from water intake but nothing your body won't be able to warm up very quickly. Temperature range I'd feel comfortable using this is from 65°- 78°. Lower than that you'll be chilly and need a long sleeve under armor style shirt, and higher you'll be too warm and need to constantly flush to be able to cool down. I do always wear a seperate CRESSI 3mm hood so keep that in mind. Seams are holding well, cuffs/ gaskets are tight but not uncomfortable. Good deal for a fairly priced wetsuit for general purposes and scuba. Spearfishing and freedivers save up and get a custom high-quality smoothskin (freediving) or open cell (spearfishing) both two pieces with built in hood. This suit is best used for watersports. I tend to get cold very easily so this wetsuit was a very pleasant suprise for being a 4/3. Perfect for any winter water temps in FL and any freshwater springs. ... show more

  • Warm suit. Doesn't let cold water flush through the zipper !
Color: Black/Black/Black Size: X-Large
I'm 5'11" 205lbs kinda stocky. I've sometimes have to wear a XXL because of my shoulders & chest but then those suits are loose in the legs on me. This fit me perfect ! I was concerned that it doesn't have a bat wing under the zipper & usually this means cold water runs down my back " But that's not the case with this suit" zipper holds out the water really good! It's got fleece inside which keeps you warm in cold water. Great suit for the $ also they packaged it nice & it didn't come all wrinkled. I've had new suits come wrinkled from other suppliers as they put the suit in a huge box & it just flopped around during shipping. ... show more

  • Absolute Piece of Garbage
I take very good care of my wetsuits and my last 4/3 was a quicksilver that lasted me 3 years. I thought switching to O'Neil was going to be an upgrade in terms of quality but wow was I wrong. Haven't even owned it a month and it's falling apart. After the first session wearing it the wetsuit tape on the crotch peeled off and the fabric on the inside started separating from the neoprene. Now the stitching on the seems are coming undone, and the key loop ripped off. (Putting the loop on the lower leg is absolutely stupid, how am i supposed open my car door balancing on one foot? Whoever designed this POS obviously doesn't surf). And I can't return because I've been wearing and already tried to repair it since I need a suit to surf in. And I know I should have bought this in person from a local shop but they were out of my size practically everywhere and I was desperate. But overall, a piece of garbage that damages the O'Neil brand name. ... show more

  • The most for your money
Color: Black/Black/Black Size: Medium
Some background on me, a swim instructor and I constantly have to be in the water for 6+ hours, 5 days of the week. This wetsuit keeps me warm and makes me feel as if I’m not even in cold water. On top of that, it’s still holding strong after 200+ hours of wear. It does rip a little at the leg cuffs but the suit itself holds strong. Will buy again. ... show more

  • I ordered down a size
Color: Black/Black/Black Size: MS
I am 5' 11 1/2 and 165 lbs. Took a chance and ordered the MS size because it had a big discount. Already owned a medium Oneill 4/3 suit and it fit well but let a bit of water in. This one is snug and pretty sure that no water will get in. Got it on and off with ease. Figure with a bit of use it will loosen up anyway. Very well built wetsuit. Happy with purchase. ... show more
