Surfing wetsuits are a breed unto themselves. To begin with, there are cool, surfer-dude designations used to describe the different styles of surfing wet suits.
The first is the spring suit which has short legs and short arms and is used to keep the upper body warm and has a thickness of materials of about 2mm. Short Johns are like spring suits but without the sleeves and are also usually 2mm thick. Long Johns have full-length legs and are mostly about 2mm thick. Full Suits are self-explanatory, the most commonly used — especially in colder waters — whose thickness is determined by the temperature of the water the surfer usually finds himself in.
