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

Love O'Neil wetsuits

So stoked on the Epic 3/2. Comfortable suit that keeps the chill off. O'Neil is the only suit I've purchased since 1978. Do you remember the Animal Skin 5/3? Perfect for Point Mugu winter sessions. My first wetsuit.

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.

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.

Highly recommend

Great suit for the price point-last suit was a chest zip and I have found it refreshing not going thru a reverse birthing process trying to fight my way INTO a small opening. The back zip is SOOO much more less stressful-and with the new style double sealing neck closure in conjunction with a great zip system-there is virtually zero Back flushing when under water. This suit kicks ass.

Don't Get This Wetsuit!!!

Don't get this wetsuit!!!! It SMELLS!!!! Apparently O'Neil is known for this. It smells like the skunkiest you know what you've ever encountered. I had to put it outside! I'm afraid to ever wear it because I read people still stink after they showe.

Poor construction. Leg seam tore open on day one. Loved my old O’Neil suit but this model is really poorly made

Not made like they used to be!

It is great for the price but definitely not the same manufacturing O'Neill had years ago. The Velcro gets stuck to the neoprene and rips its outer layer, O'Neill knows this because there is a mark of where to exactly stick the Velcro for storage. While this is a good feature since the Velcro it is in fact strong, it is impossible to keep the Velcro from sticking to the rest of the suit while donning or doffing the same. Also I had to repair the Velcro rubber tab with Seal Cement because it became unglued after the first use. The suit also runs a bit long on the legs compared with my other O'Neill wetsuits. The suit is very comfortable and does its job keeping you warm, but I expected more from this brand when it comes to craftsmanship. If you are a beginner diver or just do very little diving,then this suit will suit your needs just handle it with care, but for the veterans and the professional divers , look elsewhere. My diving friends are all professional commercial divers and SCUBA instructors like myself, so I will not recommend this to a friend!

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.
