Bring the piece back to the HACOY Showroom at Maistraße 21 in Munich for our Circular Orbit programme, where it is repaired, reworn or reclaimed rather than discarded.
Unsold and sample pieces stay in circulation through Revivewear resale and our Circular Orbit programme. They are not destroyed.

Designs each piece to be both a statement of style and a functional part of the modern wardrobe.

Founded HACOY in Munich in 2021 on one idea: better, not more.
