The new Ultra Tri Ali'i Women's Racerback Top was designed as part of Zoot's limited edition Kona collection. This top perfectly complements the six inch shorts from this lineup, and it relies on the same proprietary fabrics and fit technologies that have made Zoot a leading choice among competitive triathletes around the world for the past 30 years. Zoot constructed the Ultra Tri Ali'i from a blend of polyester and spandex, which hugs your body to speed up moisture transfer and evaporation, keeping you cool and dry as you run and ride. It also works to support your muscles, which decreases fatigue and energy, so you can cover ground with less wasted effort. The racer back lets you move your arms and shoulders freely, and the built in bra supplies support when you're on course. Although the Ali'i Racerback isn't the most technical piece in Zoot's lineup, it does employ many of the features found in Zoot's most high end gear. This includes the proprietary SeamLink construction, which designs the seams in such a way as to avoid rubbing and chafing. The Ali'i also has three rear pockets for gels and tablets, and it features UPF 50 sun protection to save your skin from the bright Hawaiian sun.
