About Orca: In 1992, Scott Unsworth, a former New Zealand age-group triathlon champion, stopped competing due to a chronic back injury. Through his experience working as a swim coach, and from his first-hand experience in triathlon competition, Scott saw that the wetsuits being used by triathletes were completely inadequate for swimming, and he started a company called Performance Speedsuits Ltd. Scott's early designs were directly inspired by his personal experience with the demands of the sport, and to this day Orca's designs and features are the direct result of working with professional athletes. In the five short years since Orca was launched in 1995 the brand was able to firmly establish itself as a favorite among the world's elite triathletes, and at the 2000 Olympics in Sydney, Australia two thirds of all triathlon competitors wore Orca Speedsuits in the swim leg of the event. Orca products continue to be designed by and tested on athletes, not computer models, so you can be sure that the designs, materials and production techniques that go into Orca's championship-winning suits are always on the cutting edge.
