Questions & Answers

DR F : Sizing recommendations? I am 5'10" 210, 17" biceps, 26" Quads, 44" chest, 48" shoulders and a 43" waist. ThanksMario C : XL or 2XL.. Arms and legs will run a little long..
KYUNGUN K : Can I use this suit for diving?SUNG HYUN L : yes you can. I always use this suit for divingSTEPHEN H : Absolutely you can dive in this suit. With it being a thicker suit just make sure before going on the dive what weight you will have to add to counter act.MATTHEW B : Totally good for diving. Functions more like a 3mm than a 4mm suit temperature wise.DEVIN R : Yes, I've used the epic 4/3 for multiple dives
Shopper : Are the seems taped?LAURENCIO G : No the seams are not taped, however, they are very well stiched and I have had no issues. Love the suit and recommend it.
HERIBERTO S : what is 4mm and what is 3mm?MATTHEW B : The forward core/torso is primarily 4mm with 3mm surrounding the back zipper for flexibility, the arms and legs are 3mm proximally and 2mm distally. Overall a super comfortable suit and a great value.MICHAEL G : IIRC the arms and lower legs are 3mm, the rest is 4mm. My advice is to just get one, especially if you have an athletic build and are hard to fit. I've been very pleased with mine, and Leisure Pro's service and prices beat out most. - MikeDEVIN R : With all neoprene wetsuits, the first number (4mm) represents the thickness of the neoprene in the torso area and the second number (3mm) represents the thickness of the neoprene in the extremitiesBLAINE W : 4mm and 3mm represent the thickness of the wetsuit in millimeters. The heavy wear parts of the suit are 4mm thick and the other parts of the suit are 3mm thick. The thicker the suit, the more body heat can be retained and thus the warmer the wearer stays.SUNG HYUN L : torso and thigh are 4mm, below knee is 3mm
Shopper : Why Did You Choose This?JELANI H : ComfortCHAD W : needed new suit for our dive tripJOHN W : Good news bad news. Still diving but I'm becoming a geezer so my 3/2 isn't warm enough any more for long drift dives. Also good for summer white water when water isn't snow melt.LAURENCIO G : Buying because me 3/2 is not enough for diving in Costa Rica. Will try the 4/3 and leave a review as to how well it works.HARLY Z : recommended by staff at divers direct as best value, then found it here for $20 cheaper

Fits true to size looks great

It fits true to size being a tall thin guy can be hard to find a wet suit that fits true to size. Recently used 40-50 degree water at it kept me comfortably warm. So far the quality is really good. The zipper is heavy duty compared to previous wetsuits used. Seem stitch quality is high. It?s a good looking wetsuit.

Great wetsuit!

Northeast USA surfer. Had the Epic 3/2 and bought the 4/3 as it got colder. You can really feel the difference in warmth! A bit tight across the shoulder (I wasn't able to compare it to a large) and possibly the large is a better choice when nearing the top end of specs/size. Durable and holding up well. Great choice for the price!

Very good seal hardly any water gets in - but difficult to remove the suit over my feet - maybe the more expensive suits are made of neoprene that stretches better

Great wetsuit.

I use suits larger than recommended so I can't advise on that but I've used oniell wetsuits since 1982 and the quality is always there. These days there's so much selection The Epic 3/2 is a great wetsuit for the price point you can count on it.

Best wetsuit ever!!!!

I was finally able to try it in colder weather. It did not disappoint. It is by far the warmest wetsuit I've ever owned. The quality is outstanding. I'm going to enjoy this for a long time!

love it

i really like this wetsuit. the only thing is that the shins fill up with water every time i am getting out of the ocean. it's like a big funny bloated bottom leg until i bend over and release the water out of the bottom. i don't know if that's a sign the fit isn't right or what. it's hard to imagine it being any tighter, the fit feels great for me besides that. either way, it keeps me warm and very easy to move in.

Great suit

I bought a medium short and it fits like a glove. While it feels tight on dry land it is just right in the water and gives all the flexibility you need. Because of the fit, there are no voids to allow excess cold water to enter. I use it in Santa Cruz, ca and it works well.

Solid wetsuit

Bought as a gift for my boogie-boarding son who uses it in Northern California waters. Keeps him warm enough, but not hot, in mid to high 50?s water temp. Flexible enough for most activities. Looks good. Solid wetsuit.

Great suit. I opted for the 3/2 over the 4/3 and its plenty warm in 55 degree water. I use it for water skiing and it has great flexibility for such a warm suit.

EPIC 4/3MM BACK ZIP FULL WETSUIT,

By Dean R.

Great wet suit I've had 3 of them .I surf a lot so I go through wet suits. I do wish that the Epic 4/3 3XL came in the chest zip style and still fit like the back zip. Just because I'm a big guy doesn't mean I don't want to look cool .lol also can you guys give us a bit more tab at the locked in neck flap really hard to open and velcro is so strong that it damages the wetsuit.

The Epic has many of the same sick features as O'Neill's high-end wetsuits, including 100% UltraFlex neoprene, double seal neck closure, LSD (lumbar seamless design) and re-engineered covert blackout zip. Clean graphics and sharp style lines make the Epic the best value in the industry. Get maximum water sport performance without the chilly sensation with O'Neill Epic 4/3mm Full-Suit. High quality 100% Super-Stretch Ultra-Flex DS neoprene provides stretch factor of 150%, soft and stretchy comfort, lightweight and improved stretch that gives you total freedom of movement while surfing or snorkeling. Suit has a covert blackout rear zipper entry that has off-set teeth an interlocking zipper that keeps water from entering at the back-entry point. The zipper comes equipped with a pull tab leash for easy self-donning and doffing. With lumbar seamless design (LSD) that reduces the amount of water entering the suit while Krypto Knee Padz keeps your knees protected from abrasions.

Suit is equipped with a double seal neck closure, has strategic zero seamed under arms, paddle zones and all seams are triple glued and double blind stitched (GBS) for strength, durability and water tight integrity. Water wicking firewall insulation ensures breathable warmth and moisture free comfort as you attack the waves. Suit has an external key pocket for easy access after your water sessions.
