The Core Mark Tee is the foundation of Onyx Series 1.
Cut from a heavyweight, structured cotton jersey, this piece is built to hold its shape, drape cleanly, and age with wear. The design is intentionally minimal — a single ONYX mark placed high on the chest — allowing the fabric, fit, and construction to do the talking.
No graphics. No noise. Just form, weight, and presence.
Designed as part of Onyx Series 1, this tee represents the brand at its most disciplined: essential, elevated, and uncompromising.
