Little things make a big difference when you're attacking Ironman length courses, so Zoot made sure the Ultra Tri Women's Tank Top takes care of the details that can make the difference over the course of a triathlon. With a body made of compressive, supportive, and energy saving UltraPowertek fabric and breathable, colorful side panels, the Ultra Tri Tank will help you conserve energy and stay cool. It also has been treated with Coldblack, a heat reflecting technology that bounces back UV rays to help keep your skin up to five degrees cooler, so you sweat less and won't overheat as easily. If you need increased cooling, the CamLock front zipper is designed to stay in place wherever you leave it, so you can increase ventilation if you feel yourself heating up. The built in Dynamic X bra provides posture improving support, so your core and back muscles don't have to work as hard to keep you in an optimal position, and Zoot's SeamLink technology ensures that minimal seams are strategically located so they won't chafe or inhibit movement. The jersey is finished with five rear pockets for increased nutrition carrying capacity, a reflective dropped back hem for extra coverage and increased visibility, and UPF 50 sun protection to protect your skin from the Kona sun.
