  • Excellent Suit for the Price Point and Warm in 50 Degree Water
With the pandemic going on and everything closed, my local pool has remained closed, and they don't know if they will open it for summer. I'm an avid swimmer (I swim at least 4 times a week), and I haven't been able to swim for 2 months now. So, I decided it was time to start considering open water as an option for my workouts, but it's only in the 60s where I live, with a smattering of 70'sh degree days lately. The lake is about 48, 50 degrees, depending on how far from shore you go. I wanted to make sure I could stay in the water for upwards of an hour and not suffer hypothermia, but I also wasn't sure I wanted a 7mm or 5mm suit, so I decided to just try this 4/3 suit, especially for the price-point. I went out for my first swim today. Ambient temp was about 65 degrees. The lake water was 48 / 50 degrees. This suit was amazing. I ordered a 4 xls because I'm a bigger guy all around and even when I shed weight, my chest is big as are my arms and thighs. The suit fit almost right. I had a little bit of roll in the arms, arm pits, legs, and crotch. Despite that little bit of roll, the suit did it's job perfectly. As I swam, I could feel the heat radiating from my body in the suit and the warm water between myself, the suit, and the lake. I swam for an hour, and I can say I never even felt chilly while in the water (aside from the exposed areas of my face at first as I eased myself into the water). In terms of fit, I did feel the water rush into my suit at the low back, because the suit is a tad too large, but it insulated well, and it kept that water warm. I'm exchanging this for one size down, but I'm sticking with O'Neil. I can't say enough great things about this suit. ... show more

  • 4/3mm O'Neil Epic Size: 2XLS (fots 5'11, 215 LBS)
Winter is here.... Need a 4/3mm O'Neil Epic Size: 2XLS (for a 5'11, 215 LBS man) Great wetsuit, great price, so nice I bought it twice! One for me, one for my son... Great for Cold (sub 50° H2O)... Not sure how much lower than 50° but definitely great for that temperature range. I'm 5'11 and I weigh approx. 215 LBS or so, so I'm not tall, but I'm not small... went with the 2XL(S) size and it is a perfect fit. Couldn't fit any better in my opinion. My son and I tested these suits for a couple of hours just floating around out in Galveston Beach (there was no surf that day, so a good day to just test them out by floating around for a while)... we couldn't feel the cold water at all the suits are GREAT, 5 Star Great! I can already tell I'm going to need some gloves and I just decided on a couple of NP Neoprene Beanies... (hard to find with Prime benefits included)... back to the wetsuit, awesome fit, awesome quality, awesome comfort, and all around awesome value for the money! Would HIGHLY recommend the O'Neil Epic 4/3mm wetsuit for anyone in the south surfing or scuba diving during winter months. Outstanding purchase! ... 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

  • 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

  • Wetsuits Arrived smelling like weed and it stinks!!
Color: Black/Black/Black Size: X-Small
This wetsuit is awesome, I bought it for my 15 y/o son to waterski in this winter. I kept the box in my office prior to wrapping for his birthday in February. Within 2 days my house started smelling like weed. After going through every room and my wife thinking I started smoking pot. I realized the smell was emanating from my office and this large Amazon box. I moved the box to the garage and the smell Followed. Thinking the smell Would go away after some use, I gave it to my son for his birthday. He has used it twice, hanging it immediately after use. The wetsuit gives off the weed smell still, completely permeating my backyard. Any clothing he wears after wearing the wetsuit reaks of pot. Even his friend who hung out in my backyard where the suit was hanging got in trouble and was not allowed to come back to my house because his mom thought he was smoking pot. It is insane. This is a great fitting item that worked well in winter but O'Neil needs to do something about the smell and come out with a product or method to remove it. Don't buy unless you want you house and rooms to smell like weed!!! ... show more
