Core Performance Shirt The shirt you reach for on your hardest training days. And your easiest ones. Built from a premium tri-blend of Polyester, Tencel, and Spandex - this isn't your average performance fabric. The Tencel gives it a softness most athletic shirts can't touch, while the moisture-wicking polyester keeps you cool and dry when things get serious. The spandex moves with you so nothing is working against you when you're working hard. The tapered athletic cut enhances your build without clinging. The subtle side shaping and chest structure give you a clean, defined look that holds up whether you're mid-session or heading into your day. Reinforced seams mean it's built to last through the kind of training that tests everything. The only thing left to do is get to work.
