You're welcome Yeah, it was a picky comment about performance, yet there are brands that care more about design than sport specific performance. Or others throwing most of their R&D resources in marketing and features that sound cool, such as graphene, carbon black, FIR (far infrared), heat retention/accumulation and other gimmicks. And it's all basic physics and textile materials performance.Ludmil wrote: ↑Sun Dec 01, 2019 11:26 amHey Nixmatters,
Thanks a lot for the technical lesson and for clearing what primarily is the goal designing a wetsuit. Not necessary, but thanks.
I wouldn't dare to ask how do you measure the evaporation effect, or the water retention of one vs other.
I am taking into consideration that Dracop is looking for 2/3 (warm climate),and he may look more towards flexibility instead of ultimate warmth. Stated before, O'Neill is more stretchy.
It's very warm as well, and by the way, I think that there are some more variables playing a heat retention role (apart from technological process of jersey lamination)
One of them is the fit, and in regard to the sizing I know what OP is talking about as I tried/owned some wetties trough the years (NP and O'Neill as well).
Water retention (soak the specimen, let it drip for predefined time, weigh it) and evaporation effect (water evaporated per area at constant air flow/temp) are easy to measure using some modified ISO/ASTM test methods and setting your own benchmark values. Unfortunately there is no international standard on surfing wetsuits. Basic thermal insulation (CLO value) is defined in EN 14225-1:2018 (diving wetsuits).
The main issue is that once your suit flushes or you're riding in 30+ knots... the Clo value has little importance.
So yes - Fit is (almost) all! One litle known fact here - very tight wetsuits (a way to get best fit and little to no flush) cause an increase in urination. And this has almost nothing to do with body temperature.
Check the size chart (esp. height vs waist) and bear in mind that if you overstretch a part of the suit in one derection, it will shrink a bit in the other.
Btw, Hyperfreak 3/2 is not in O'Neill assortment for Europe and SA. There is a good deal for 3/2+ (0.5mm thicker foam) at cleanlinesurf, XXL.
