Hello, Pirrad,
For COLD conditions, I’ve settled on an Ion single-sided, 4/3 wetsuit, a Ripcurl vest, a NP standard hood and boots.
Ion:
http://www.ion-products.com/water/men/wetsuits/quantum/semidry-43-sk/. Note: if you go Ion, suggest you get one size bigger than what their specs call up, as I found their specs were one size too small for me.
Ripcurl
www.ripcurl.com.au/shop/guys/wetsuits/vests/flash-bomb-neo-lycra-lsl.html. My vest has a Titanium lining, to reflect heat back into the body. Can’t see this feature mentioned in their range now, due to spec changes, but you’ll get the idea.
NP:
www.npsurf.com/products/protective/hoods-beanies-hats.html.The vest should definitely be worn under the wettie, but the use of the vest is dependent in the air/water temp. Use it when it’s really cold, but you don’t have to use it if the air/water temp rises. I find the vest more flexible in its use that a full, thick wettie, particularly when we get into October/November.
I can also recommend the use of a spray jacket, if, during a long session, you start to get cold, but don’t want to stop to pull on the vest. The spray jacket is also useful if you’re standing around talking with your friends in windy conditions.
Whilst I am sure that others will raise the question of the life of single-sided vs. double-sided wetties, the fact of the matter is that, although the single-sided wettie is more fragile, with care it will give a long life. I only got the Ion recently, replacing a NP 3000 4/3 which has lasted more than 8 years (and in fact I used it today whilst Supping).

For me, the features of a wettie I look for are: vertical back zip, non-choker neck seal, pre-bent boomerang arms, velcro seals at the ankles, and thin rubber cuffs at the wrists. The Ion meets most of these needs. I use a thin plastic shopping bag when pulling on the wettie over my arms and legs, to reduce stress in the wettie.
Hope this helps.
