Suits
 
Suits are used for 2 main purposes, reducing heat loss and to protect you from minor scrapes,stings and abrasions.There are 3 main types of suits : Body, Wet and Dry.
Body suits are made from colourful Lycra, nylon or similar material and provide full-length abrasion and sunburn protection. They don't provide much insulation, and are generally worn in tropical waters.
Wet suits are the most common form of exposure suit. They come in many styles, patterns and thicknesses, making them suitable for insulation in waters as cold as 10 Degree Celsius to as warm as 30 Degree Celsius. Wet suits reduce heat loss by putting a layer of insulating foam neoprene over your skin. Wet suits get their name because you get wet while wearing them - water enters at the wrists, ankles and neck and gets trapped between your skin and suit.
Dry Suits provides more insulation than wet suits by keeping you dry. They provide the most thermal protection of all suits used by recreational divers. The Dry suit insulates you with a layer of air, plus insulating material that may be an undergarment within the dry suit, or the dry suit material itself. Everything between your skin and the water reduces heat loss, and dry suits fit relatively loosely.
