O'Neill Heat 4/3 Full Wetsuit
This wet-suit is perfect in every way. Water temps from 55-70 it rocks. Surfing in SolCal Country Line surf spot I see many surfers all in the same black O'Neill Heat 4/3 and 3/2's. I have lived my life in the water. At 55 I surf, free dive, snorkel, sailing, and rappelling down cold water falls. I have destoryed many wet-sutis and this is my goto wet-suit, it is very easy to get into with rear zip. Not a fan of front zips, but have a few of them.
