The wetsuit is the accessory that symbolizes today's scuba diving, along with fins and a tank. They have come a long way since their earlier days of suit pioneers like the O'Neill brothers and their Santa Cruz surf suits to being made from a combination of neoprene rubber and synthetic fabrics. Wetsuits today contain a combination of a wide variety of fabric weaves, designs, colors, and different types of material densities. There are loads of brands to choose from, each offering their own unique properties on one of the most important parts of the scuba divers outfit, especially if diving in temperate or moderately deep waters is planned.
History of Wetsuits
Wetsuits were first made from rubber skins and were worn to keep in heat and for skin protection. More advanced suits made of neoprene, whose cellular construction traps air and water to be heated better than simple rubber. These more advanced suits were made possible by early designs of the rubber suits. However, although neoprene is more flexible, the earlier versions of wetsuits made from it were easy to rip and very hard to put on, putting it on often required applying talcum powder to the inside of the suit. As several generations passed, new breakthrough lines such as the Sharkskin and Turtleskin brands added a whole new layer of nylon sheeting to the inner suit and a textured surface which increases strength and durability.
Modern wetsuits use combinations of Lycra or other synthetic materials to replace nylon sheeting. Some brands, such as the Pinnacle Aquatics lines, feature combinations of titanium weaves and natural Merino wool to increased durability, warmth and to reduce odors. These modern suits also use layers of thicker materials to protect sensitive spine and neck areas, and have reinforced knee and elbow pads to protect the diver against chafing against rocks and coral heads.
The Way They Work
Water flows into the small pores of the neoprene foam of the suit where it is trapped and warmed by the body heat and exertions of the diver. The layer of warm water keeps the cold water from reaching the divers body by acting as a thermos bottle. The wetsuits are designed to let water come in contact with the skin. This is in contrast to the dry suit which keeps all water out. Wetsuits are usually used in waters whose temperatures range from 40 to 60 degrees. Dry suits are used in waters whose temperatures are much lower.
Types of West Suits
There are many different types of wetsuits besides the well-known full suit. "Shorty" suits have full torsos, but do not cover the entire leg and arm areas. These suits are good for warm water conditions, where the main issue is maintaining body heat at greater depths. The "Farmer John" style (now less popular than in the late 80s when it was invented) has a thickened "pants" layer that goes up around the shoulders, but doesn't cover the arms; this type is good for surfing applications where knee protection is important. In addition, there are now specialized "thin suits" for competition swimming and light dive applications; these suits offer streamlining and abrasion protection more than they do temperature control.
Wetsuit Hoods
Since over 25% of body heat is lost through the head, hoods are a very important accessory to a full wetsuit. Hoods are often made of similar materials to a wetsuit, but are somewhat thicker to prevent loss of heat around such a sensitive area. Most hoods have long "bibs" that tuck within the neck of the wet suit to protect against a gush of cold water down the neck.
Wetsuit Booties
Even though some wetsuits have integrated feet, most use separate booties that are drawn up over the legs of the wetsuit. These are usually corrugated and reinforced to allow divers to stand or push off against rough surfaces.
The Gloves
Another important addition is the Gloves. They must not only protect against cold water but must also stop sharp coral and rocks from damaging the skin. Diving gloves also have textured fingertips to help in handling gear or other objects during a dive.
Summing Up
Since the early primitive rubber casings of the early 1950s, wetsuits have come a long way. With the rise in technology and new materials and special computer-aided designs, wetsuits will continue to improve and offer divers of the 21st century new options for their diving experience. - 15438
