Do you know how divers keep their bodies warm while underwater? The warmth that they need is provided by the dry suit. The dry suit provides thermal insulation or what is known a passive thermal protection to whoever wears it while underwater. This is the suit that you normally see worn by boaters, water sports enthusiasts, divers, and those whose work always involve being exposed to cold water. The only portion of the body not protected by the dry suit are the exposed ones which include the head, hands, and sometimes, even the feet. However, there are dry suits that are designed to cover even the body’s extremities especially when the water is below fifteen degrees Celsius or around sixty degrees Fahrenheit. The dry suits are usually partnered with helmets, boots, and gloves that provide personal protection for individuals working in areas where there are unsafe types of liquids.
You may mistake the dry suits with the wet suits but they have varying uses. First off, dry suits are designed to prevent water from entering and that is the reason why they are generally used when the water temperature is extremely cold. However, dry suits can be amazingly hot in warm water and they are generally more expensive than wet suits. Dry suits are more difficult to dress into and divers find it very complex to wear because the suits have to be inflated and deflated depending on the depth of the dive. This is very important because the incorrect inflation of the dry suit may cause a sudden squeeze when on a descent or uncontrolled rapid ascent because of over buoyancy.
The dry suit is made mainly of waterproof material usually from a membrane material like neoprene, foam rubber, or a combination of both and this serves as the waterproof shell of the dry suit. For convenience, divers may use membrane dry suits. Because of their thin material nature, they can easily be donned just as long as you choose the oversized ones. They are usually made of vulcanized rubber or laminated layers of nylon and butyl rubber which makes them very hard to stretch. To be able to move easily underwater, a baggy and oversized membrane dry suit is advised. Nevertheless, the membrane dry suit alone is not suitable for water in low temperature and in order to make it apt for cold water, the wearer must put on an insulating under suit which is generally made of polyester or synthetic fiber.
Care must be practiced at all times in order not to pierce or tear the membrane dry suit since your buoyancy and the insulation mainly depends on the membrane dry suit being pristine and the gas pockets without a single hole. Understandably, the under suit is not required when diving in warm waters. The neoprene material, which is usually made of synthetic rubber, is also often used to cover the neck and ankles and they can be designed to contain thousands of tiny air pockets in order to add to the buoyancy of the wearer.
