Sacra — Unbroken Vow
$595.00
Sacra — Unbroken Vow draws from Etruscan symbolism, where the interwoven knot represented continuity, unity, and strength sustained through commitment. The form reflects the idea of alignment held over time — forces bound not by constraint, but by shared purpose and clarity of intention.
Set upon a deep black field, the knot is rendered in luminous white, allowing its structure to emerge with composed contrast. Positioned close to the heart, the emblem conveys stability and protection through cohesion rather than force. Its uninterrupted lines suggest resolve that does not fracture under pressure, but endures through balance and restraint.
Unbroken Vow is created for those who value constancy as a form of power. It does not declare loyalty; it embodies it. The piece transforms an ancient symbol into a modern expression of assurance — where commitment is internal, strength is sustained, and alignment becomes a lasting presence.
This luxury designer sweatshirt is part of the Sacra series — produced in limited quantities and not intended for continuous restock.
