The Core Quarter Zip is built from a four-way-stretch seamless knit that hugs the body and moves with you through every rep, run and stretch.

The half-zip stand collar adjusts coverage in seconds while flatlock seams and thumbhole cuffs keep everything locked in place during high-output training.

Sculpting, breathable and endlessly layerable, it transitions effortlessly from warm-up to cool-down without losing its shape.
