How Speedo Created A Record-Breaking Swimsuit

In 2009, Speedo’s research team began to brainstorm innovative ways to help swimmers go faster. The polyurethane bodysuits that contributed to an astonishing number of swimming world records over the previous 18 months had been banned. To think outside the box, the Speedo representatives met outside the lab, joining academics, coaches and research consultants at hotels, conference centers and even an English country house to spawn ideas, ideas inspired more by Captain Avengerthan Mark Spitz.

“Lots of conversation was had around wild and wacky ideas,” says Joe Santry, the research manager for Speedo’s Aqualab in Nottingham, England. “Some of the initial sketch concepts brought to the table looked like a superhero suit with a sleek cap, goggle, and suit combination that wouldn’t look out of place in a Marvel comic.”

They were trying to replace the now infamous full-body LZR suit. Dubbed “the rubber suit,” it compressed a swimmer’s body into a streamlined tube and trapped air, adding buoyancy and reducing drag. Speedo says 98 percent of the medals at the 2008 Olympics were won by swimmers wearing the LZR. Michael Phelps set world marks in seven of his eight events at Beijing wearing the suit, but applauded its ban.

The new rules, in effect since 2010, permit only “jammers,” suits from the kneecap to navel for men, and from the knee to shoulder for women. The fabric must be air permeable, and a suit may not have any fastening devices such as a zipper, a response to companies that began creating wetsuit-like neoprene suits after the 2008 Olympics.

Ultimately, Speedo decided to rebuild not only the suit, but create a “racing system” that it claims combines the suit and the goggles and cap working in synergy to reduce drag and improve performance.  (...)

For the suit, the team spent a year inventing a new fabric that creates compression changes across its surface where more lycra is knitted into some areas. In the end, Fastskin is Spanx on steroids, compressing a body three times more than the LZR. The suit constricts the stomach the least and the chest, buttocks and hips the most, attempting to mold swimmers into an unblemished tube.

Speedo has applied for nine patents for the Fastskin-3. The company says only six machines in the world are capable of producing the compression fabric; it owns all of them.  (...)

“It’s like miles per gallon in a car,” Santry says. “You can swim at the same speed, but use less fuel. It allows a swimmer to go harder for longer.”

Speedo scanned its key athletes to create a 3-D avatar to size the suit. Just wearing the Fastskin requires athleticism. Some female swimmers, who step into the suit through an armhole, reported it took them as much as an hour to wriggle into it on their first attempt. Santry says it can be done in 10 to 15 minutes with practice. “The first time you do it, it’s daunting,” he adds. “There’s quite a bit of compression in the suit. It can feel a bit alien.”
