About Zoot: Zoot Sports(TM) was founded in Kona, Hawaii: the home of the Triathlon World Championships. Chrystal Nylin, a Hawaiian native, recognized the need for a cross-functional suit for athletes competing in triathlons. As a solution to having to use transition as "changing areas," she sought to find product solutions for multisport athletes. Nylin began sewing pads into run shorts, experimenting with swim fabrics, and attaching run singlets to bike shorts to eventually create the Zoot one and two-piece racesuits for triathletes competing in Ironman. In 1996, Zoot Hawaii moved to the mainland and expanded the product line. It has now grown to be a global premier endurance sports brand, distributed across 22 countries and has introduced the first Triathlon-Specific Footwear Line. Zoot continues to draw on its history in the sport and its athletes to deliver the most comprehensive, technologically-advanced and complete multisport product line in the world.
