Fairly tight nylon pants which enjoyed a period of popularity in the mid-1980s. They had zippered patch pockets -- the usual two in the front and two in the back, plus one or two on each leg. Sometimes, they had zippered ankles. The existence of parachute pants is an indication that maybe fashion in the '80s sucked just as hard as it did in the 1970s.

And now some Evil Corporate Empires are trying to bring parachute pants back -- this time, they're calling them "para pants", but we won't be fooled this time!
