Given that triathlons require a wide array of movements, we understand why manufacturers find it difficult to produce a single jersey to accommodate every discipline. That said, if the Zoot Performance Tri Men's Sleeveless Jersey is anything to go by, it's something that's eminently doable. By forgoing sleeves, the Performance Tri allows unfettered arm movement. It also uses Zoot's SeamLink technology, which constructs low profile seams with extra stretch, adding mobility and nearly eliminating chafing. The Performance Endura fabric hugs your skin to promote moisture transfer and evaporation, helping you stay cool, while multiple mesh panels and a locking front zipper provide additional options for breathability. Like all of Zoot's triathlon gear, the Performance Tri also features reflective details, UPF 50 sun protection, and a dropped back hem for extra protection and coverage, along with four back pockets one zippered to secure all your gels, salt tabs, and key gear while you're out training or racing.
