You read right: extreme ironing — part sport, part spectacle. Press garments while kayaking, rock climbing, mountain biking or doing any other outdoor activity you like. (Since extreme ironers must wait for the invention of solar- and battery-charged irons, they heat their irons with portable gas burners, campfires and generators.)

The sport was born seven years ago when a young man named Phil Shaw … and his roommate, Paul Cartwright, did ''a spot of ironing whilst rock climbing,'' Mr. Shaw said, while skiing the French Alps and after scrambling to the tops of tall trees in the Black Forest of Germany.

Now, countless handkerchiefs and pillow cases later, and after stretching to the corners of South Africa, Japan, Croatia and Chile, extreme ironing is coming to the United States, hoping to appeal to the spin-cycle superhero, the wash-and-wear wonder woman in all of us.
