Buildup Half Zip - Club Navy
A technical layer for the work in between.
The Buildup Half Zip is a lightweight performance layer designed for training, warm-ups, running, and cooler movement days. Its streamlined athletic fit sits close to the body while flexible stretch allows you to move without added bulk.
A half-zip neckline makes airflow easy to adjust as your session changes, while the minimal construction keeps the silhouette clean enough to move beyond training.
Layer it. Train in it. Keep moving.
