Our story

KOVROS USA is the maker of OnCollar™, a patented attachable collar cover (collar sleeve) that changes the look of a regular shirt with a permanent collar.

Every KOVROS dress shirt is slim fit, 100% cotton and comes with a matching OnCollar. Slip it over the collar for a bold contrast look, or leave it off for a clean classic shirt. One shirt, two styles.

OnCollar for business

OnCollar can be made with designer, custom or plain fabrics. You can print or embroider on it: add your company logo, a promotional message or a QR code, and wear it over an existing dress shirt collar. It's ideal for teams, events and brand promotion. Ask us about custom and wholesale orders.
