Once upon a time there were 5mm wetsuits and 3mm wetsuits and not a lot in between โ no dedicated suit for the shoulder seasons either side of winterโs icy head. Thankfully those dark, illogical, and slightly too warm/cold times are over, with more and more surfers cottoning onto the virtues of the 4/3. Add a hood and all the recent advances in wetsuit tech and youโve got a suit that might even last you all the way through winter. | | |
