A dry suit or drysuit provides the wearer with environmental protection by way of thermal insulation and exclusion of water,[1][2][3][4] and is worn by divers, boaters, water sports enthusiasts, and others who work or play in or near cold or contaminated water. A dry suit normally protects the whole body except the head, hands, and possibly the feet. In hazmat configurations, however, all of these are covered as well.[5]
