Concealment: Trenchcoat
A set of primitive "SCUBA" equipment. This includes a set of flippers, allowing you to double swimming speed, goggles, allowing unimpeded vision underwater, and a weighted "air bag". You can use the air bag to fill your lungs underwater, permitting you to stay underwater for twice as long before having to surface or drown. Several air bags can be used, but they are very bulky and difficult to swim with, causing one point of Impairment per bag if you carry more than one.
