For either realm, dressing for success is not so different in that NASA\u2019s space suits have informed scuba divers\u2019 drysuits. Although modern versions of the drysuit have been around since the late 1980s, they remain a novel sighting for many beachgoers. Drysuit fabric keeps water out so that I stay dry except for my head and hands, which I encase in good old neoprene (wetsuit material). By keeping most of my body dry, I can conserve heat without wasting energy warming the layer of water between my skin and the neoprene (the blubber-layer concept behind a wetsuit). Because a drysuit shell provides no warmth, I don layers of polar fleece underneath. A drysuit\u2019s valves allow for air to enter and exit the suit while keeping water out. To inflate my suit for buoyancy and comfort, I press on the inlet valve located on the drysuit\u2019s upper chest area. A hose provides the conduit from the valve to the very same air tank from which I also breathe. To release, I press the exhaust valve on the upper arm. Below the surface, I still need to regulate air in and out. For instance, as I sink, I get heavier and heavier due to increasing outside pressure that goes hand in hand with increasing depth. This results in my being squeezed like those food storage devices that suck out the air in a bag (drysuit) of leftovers (diver) and controlling my descent (a braking system).
