A wetsuit is a garment worn to provide thermal protection while wet. It is usually made of foamed neoprene, and is worn by surfers, divers, windsurfers, canoeists, and others engaged in water sports and other activities in or on the water. Its purpose is to provide thermal insulation and protection from abrasion, ultraviolet exposure, and stings from marine organisms. It also contributes extra buoyancy. The insulation properties of neoprene foam depend mainly on bubbles of gas enclosed within the material, which reduce its ability to conduct heat. The bubbles also give the wetsuit a low densit

300px|thumb|A maillon with the gate open and closed. A maillon, maillon rapide or quick link is a metal link, similar to a carabiner. Maillons have a threaded sleeve which tightens over a thread, as opposed to a hinged gate like a carabiner, making them stronger, but more difficult to use. Like carabiners, maillons are available in a range of shapes and thicknesses (i.e., strengths), and often offer greater versatility over carabiners as their different shapes and lack of hinged gates allow them to be used in multi-directional load situations.
