For what temperature use? San Diego March water is 58 degrees.

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.

I am 6ft 3 and weigh160lbs and chest size is 37. according to your chart would a st work best?

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.

I’m a man. 6’3. 250lbs. 43” waist. 43” hips. 45” chest. What size is best for me?

I am 6’2 & 230lbs. XL for me is perfect. XXL probably best for you

What type of stretch does this suit have?

Wetsuit is made from O'Neill's Ultra Stretch Neoprene: incredibly soft premium material has superior feel, flexibility, and elevates performance in the water.
