Behold swimming superstar Michael Phelps in the Speedo LZR swimsuit: He resembles a merman, all slick and shark-colored, his body fully corseted in what the manufacturer describes as "the world's lightest, most powerful and water repellent swim fabric."

The claims seem true: In races all over the world, swimmers wearing the LZR have been smashing speed records.
