I seen a guy wearing a short wetsuit over a full 3mm wetsuit he seemed to reckon it worked ok instead of buying a winter suit as he hardly gets surfing over winter.
Has anybody else tried this i would've thought it would be more restrictive wearing 2 suits but he reckoned it wasn't too bad.He said he got the idea from diving as a lot of divers wear short suits under or over their full suits for extra heat.
