The Zoot Performance Tri Full Zip Men's Tank Top blends innovative paneling and advanced fabrics to give your race day an extra boost. Cut from Zoot's Performance Endura fabric, this tank supports your muscles while pulling moisture away from your skin. It also dries quickly once you're out of the water to keep you dry and comfortable from T1 on. It features a form fit with a slightly elongated back, and the fabric provides a UPF rating of 50 to keep the sun's rays from damaging your skin. A full length zipper allows you to customize the amount of ventilation, and, for your longer races, lower back pockets conveniently hold your gels and salt tablets. The Performance Tri is finished with a host of additional features, including a dropped back hem for full coverage and plenty of reflective details. It's also constructed with Zoot's proprietary SeamLink technology, which keeps the seams flat to prevent chafing while adding mechanical stretch to ensure that there aren't any dead spots that would compromise your mobility.
