Core Performance Racerback Top Built for the work. Designed to move with you through every rep, set, and mile. The racerback cut gives you full range of motion without anything getting in the way. The open-back design keeps you cool when things heat up. And the front seam detailing gives it a clean, structured look that holds up from warm-up to cooldown. Crafted from lightweight moisture-wicking performance fabric that pulls heat away and keeps you focused on what matters — the training. The contoured silhouette fits close without restricting. Because gear that moves with you is gear that works for you. Pairs seamlessly with the Core Performance Shorts for a complete set built for the way you train. The only thing left to do is get to work.
