Swimming Wetsuit Design Timeline
Inventor Lawrence Wright files patent for “Swimming Garment and Life Preserver,” a pair of swim trunks with a flotation belt made of rubber for safety in the water.
Rubberized swimming garments gain a reputation for warmth, added protection against painful abrasions caused by underwater coral or rocks, and effortless movement in the water.
Rubber becomes the norm for surfers, who visit tailors with custom designs for full-body “underwater suits” made of neoprene to extend their time in the water.
At the Bass Lake Triathlon, Dan Empfield notices a handful of swimmers wearing surf wetsuits: “The water was cold, we were standing in our Speedos in snow waiting for the gun to go off. Professional triathletes Scott Tinley and Gary Peterson swam in what appeared to be just their surf wetsuits, and they didn’t swim slow.”
Empfield conducts a series of tests to investigate the impact of wetsuits. His original hypothesis: Staying warm in the water means muscles move more efficiently. The reality: A buoyant swimmer is also a faster swimmer. Empfield goes all-in on this discovery, developing the first triathlon-specific wetsuit prototype.
Empfield’s innovation becomes a necessity for the competitive triathlete—if you didn’t have a wetsuit, you were certain to enter T1 at a large disadvantage. Ironman gets in on the action, developing its own licensed wetsuit to compete with Empfield’s Quintana Roo wetsuit (Ironman’s wetsuit manufacturer eventually split off, and is now the brand Blueseventy).
Yamomoto develops Super Composite Skin (SCS) rubber. “Before, neoprene used in triathlon wetsuits tore very easily, was tacky, and tended to stick to itself,” says Blueseventy CEO John Duquette. “The SCS coating eliminated that, and is one of the biggest discoveries in modern wetsuit technology.”
More triathlon wetsuit manufacturers enter the fray, experimenting with a variety of features, including two-piece wetsuits, offset zippers, thinner necks, advanced leg openings for removal, magnetic closures, and strategic flotation panels at varying points around the body.
Blueseventy introduces the first line of wetsuits made specifically for women.
Wetsuit manufacturers continue to optimize their design. On their radar: Eliminating hard zippers, overall neck comfort, easier (and faster) removal.
