If you're racing triathlons in frigid weather, we feel sorry for you. If, however, you're racing in hot conditions like the rest of us, the Zoot Ultra Tri Tank will make your life easier. Now, we can't say it'll cut huge chunks off your time, but it will help you stay comfortable, cool, and well fueled, so it will be easier for you to race to your potential. How does a tank help you stay well fueled' Well, the Ultra Tri has not three, not four, but five back pockets, so you can load up with water and energy gels before you hit the road. That's probably its most basic feature, though. More excitingly, the UltraPowertek fabric compresses your muscles to reduce vibration and fatigue, while the strategically located side panels and mesh inserts help you stay cool and feel supported. Best of all, the whole tank is finished with Coldblack, a heat reflecting treatment that keeps your skin up to five degrees cooler than standard fabrics, so you won't overheat nearly as quickly or lose as much to sweat. Small touches make the Ultra Tri race ready, too, like a dropped back hem for extra coverage and UPF 50 sun protection to keep your skin from burning. Reflective details help you stay visible during training sessions, and Zoot's unique SeamLink technology keeps the Ultra Tri from rubbing you the wrong way, which is more than a minor irritation during Ironman length triathlons.
