MN Lakeman:Not the case IMHO - I tried on 4 different makes & none of them fit nearly as well as both of mine. If you check out the website of any wetsuit manufacturer, you'll find a size chart detailing various measurements. I found that in most cases, O'Neill in any men's size, was 2" or more smaller in the waist & hips than all the others. It sort of makes sense - a company starting out making neoprene for athletic surfers (?). Again, if you have the right fit, the little difference in neoprene density or whatever, you're going to be warmer.
I agree that O'Neill's cuts are far better than most manufacturer's. They have much more room in the thighs, chest and shoulder without the waist becoming huge and baggy. I just checked the link in Ron Frank's post. O'Neill is advertising that their diving wetsuit is made with "80% Ultraflex DS." This is the same material in the same percentage as used in the Heat and Psycho I suits, so perhaps there's no real difference between their dive and surfing suits. Incidentally, you might also want to check into the Xcel suits. My son prefers them to O'Neill though I like O'Neill better. They started as a surfing company and later began making diving wetsuits. My fundies instructor used one of their diving suits and liked it alot.
