Wet suits are worn by watersports enthusiasts because they provide thermal insulation, abrasion resistance and a certain level of buoyancy. Wetsuits are made of a flexible material called neoprene. Different types of wetsuit are made for different uses and for different temperatures. Suits range from a thin (2 mm or less) 'shortie,” covering just the torso, to a full 8 mm semi-dry, usually complemented by neoprene boots, gloves and hood. Generally speaking, the thicker the suit, the better it is able to insulate. Some modern wetsuits incorporate Merino wool and titanium fibers to add warmth characteristics, while keeping the thickness of the suit to a minimum. Another important feature to keep in mind is how the suit fits. If the suit is too tight, you might experience difficulties in paddling, moving or even breathing. A loose fit, on the other hand, will allow water to escape from between the suit and the body, taking the body's heat with it.
