Wet suits provide body warmth while you engage in water sports. Although the suits are commonly worn for scuba diving, wet suits have also been designed for triathlons, water skiing and surfing. Swimmers who work out in cooler waters often wear the suits as well. You can purchase wet suits sized for men, women and children.
Configurations
You can choose from several wet suit configurations. Wet Suit Gear notes that a full-body wet suit is a one-piece garment with long sleeves. A “Farmer John” wet suit is a one-piece sleeveless suit that can be paired with a jacket for an extra layer of warmth. A “shortie” wet suit features short sleeves and knee-length legs, and is appropriate for warmer water. Wet suit accessories include neoprene hoods, gloves and dive boots.
Materials
Most wet suits are made of neoprene, which is a manufactured rubber that's insulated and waterproof. The website for Dick’s Sporting Goods notes that the neoprene fabric is usually bonded with a nylon laminate that resists abrasions. This feature helps to prevent tearing if you scrape the sea bottom. If you’re swimming or diving in warm water, you’ll find thinner Lycra wet suits that can include a light layer of insulation.
Features
Because wet suits can be used in a cold environment, manufacturers have added features that enhance durability. Sierra Trading Post notes that many suits have taped seams that strengthen the stitching and help to keep out water. Some wet suits also have rubber seals, or gaskets, that help exclude water at the wrists and ankles. Finally, wet suits have padded knees for kneeling on the sea bottom.
Dry Suits
Dry suits are used for cold water, or for longer dives in slightly warmer water. The Professional Association of Diving Instructors notes that full-length dry suits begin with an inner layer of insulation. You'll also wear a “shell suit” that protects against water intrusion with waterproof seals at the wrist, ankles and neck. Pair your dry suit with neoprene gloves and a hood. In cold water, wear dry gloves and hoods.
Considerations
When choosing a wet suit, Best Scuba Diving Tips recommends considering the temperature of the water in which you’ll dive or swim. Cold water requires more insulation and therefore a thicker wet suit. In addition, a larger diver needs less insulation than a smaller diver. Finally, consider your planned level of water activity. If you move vigorously, your body generates more heat and you will stay warmer.
Sources
You can find a good selection of wet suits at scuba diving shops. Suits from several manufacturers will likely be featured, along with men’s, women’s and children’s models. Sporting goods stores might feature wet suits as well, although your selection will be more limited. Finally, online wet suit retailers carry wet suits. Some retailers specialize in certain types of suits, such as those for triathlons or surfing.

Good article. Wetsuit thickness is something that is often overlooked. A 3/2 wetsuit is the thinnest wetsuit available for surfing.
The numbers 3/2 represent the thickness of neoprene used in this wetsuit. 3 stands for 3 millimeters and 2 stands for 2 millimeters.
This means that a 3/2 wetsuit is made from neoprene of two different thicknesses, the thicker one is usually used on the body and legs and the thinner is used on the arms and crotch area.
The reason for this is improved flexibility of the wetsuit. Thicker neoprene keeps your core warmer while thinner neoprene allows for more flexibility where you need it.
