A pressure suit is a protective suit worn by high-altitude pilots who may fly at altitudes where the air pressure is too low for an unprotected person to survive, even breathing pure oxygen at positive pressure. Such suits may be either full-pressure (i.e. a space suit) or partial-pressure (as used by air crew). Partial-pressure suits work by providing mechanical counter-pressure to assist breathing at altitude.
Diving suits that protect the wearer from excessively high pressure are called atmospheric diving suits. Pressure suits in general are examples of environmental suits.

Famous quotes containing the words pressure and/or suit:
“By school age, many boys experience pressure to reveal inner feelings as humiliating. They think their mothers are saying to them, “You must be hiding something shameful.” And shucking clams is a snap compared to prying secrets out of a boy who’s decided to “clam up.””
—Ron Taffel (20th century)
“The people needed to be rehoused, but I feel disgusted and depressed when I see how they have done it. It did not suit the planners to think how they might deal with the community, or the individuals that made up the community. All they could think was, “Sweep it away!” The bureaucrats put their heads together, and if anyone had told them, “A community is people,” they would not have known what they were on about.”
—May Hobbs (b. 1938)
