## Questions & Answers

**Q: For what temperature use? San Diego March water is 58 degrees.**
A: Any answer saying this appropriate for 40 degree water is utterly incorrect. 2/3 wetsuit is for very long snorkeling (3-5 hours) in tropical (Caribbean) short dives in temperate (eg Mediterranean).  5mm for deep but short scuba or long snorkeling in temperate waters. 40 Degree is on the edge between 7mm for short dives and dry suit for a couple of dives. In 40 degree water you want 7mm with 5mm to 7mm hood, gloves, booties.

**Q: I am 6ft 3 and weigh160lbs and chest size is 37. according to your chart would a st work best?**
A: Just received my O'Neill. I'm 6'4" ish and 165#. The Medium/Tall is a great fit . . . maybe a hair short in leg length.

**Q: I’m a man. 6’3. 250lbs. 43” waist. 43” hips. 45” chest. What size is best for me?**
A: I am 6’2 & 230lbs.  XL for me is perfect.  XXL probably best for you

**Q: What type of stretch does this suit have?**
A: Wetsuit is made from O'Neill's Ultra Stretch Neoprene: incredibly soft premium material has superior feel, flexibility, and elevates performance in the water.

### ⭐⭐⭐⭐⭐ Great
*by R***M on July 16, 2026*

Worked perfectly in the cool water.

### ⭐⭐⭐⭐⭐ Can't wait to try this new O'Neill 3M/2M suit. Perfect fit!
*by T***R on March 27, 2019*

The fit is perfect. The leash to zip it up is the perfect length. The cuffs at the sleeves and ankles feel like very little water if any will come in. I could already feel my body heat retention not leaving the suit so again I feel confident I won't be shivering at 25 and 30 ft depths. I will update again after my first freedive in a few weeks at Lake Ouachita at Blakely Mountain Dam. Last year's wetsuit was a Dark Lightning 3 mm and I floated like a cork. If you were snorkeling, I guess that would be a good thing as you wouldn't have to work so hard to stay on top of the water. But the drawback was two things. First, water came in at the sleeves and the ankles which I tried to avoid and yes it was cold. When you are a freediver, you want to stay warm, but you DON'T want to work yourself to death trying to swim down 15 or 20 ft. The Dark Lightning suit wore me out because when I got to the bottom of the lake, I didn't have any air left to enjoy the dive because I kicked so hard to keep from floating back up to the top. The reviews on the O'Neill state the suit is not very buoyant which will also be a big plus if indeed that is the case. Also, hopefully this year I will be making the trip to Beaver Lake to their dive park there and reviews already state the water there is much colder than most lakes in Arkansas, but much to see. Promise to update review after first successful excursion with my new O'Neill wetsuit. Just as a guide for the fit, I am 5'11 and 170 lbs. and I ordered the common M size with the perfect outcome for the fit.
