Types of Wetsuits top of page Spring Suits have short legs that fall just above the knee, and either short or long sleeves. They were apparently named in some warmer climate, since here in the northeast you would almost never wear a spring suit in the spring.
Full Suits are the standard wetsuit with long sleeves and long pants.
These cover a wide range of warmth, depending on such factors as thickness of neoprene, types of seams, types of closures, etc. Farmer Johns are a sleeveless suit with long legs. They're sometimes called Long Johns. They're a good choice for cold water when the air is warm. Combined with a wetsuit jacket or top they can offer some versatility in warmth, but you will lose a little in flexibility and comfort going that route as compared to a fullsuit.
