During the winter and really cold times nothing beats a dry suit. I wear a NRS Event. During runoff, for surfing I wear a full, 4/3 wetsuit. That is great and I can soak in the Ark at 3500cfs like a hot tub, but it is not very good on a cold day when it is windy and I am paddling to whole time, i.e. not swimming.
In summer I go either board shorts and synthentic shirt if it is warm or I go with a farmer john/shorts wet suit from NRS under my board shorts and shirt so I can still look all stylie
, but have some warmth...
otherwise it is the usual, helmet, PFD, booties, etc.
