1. Maintain High Visibility: Any additional to the vest should not obstruct or diminish its high-visibility features, such as fluorescent materials and reflective strips.

2. Comply with Standards: Personalization must not compromise the vest’s compliance with safety standards. It is essential to ensure the vest continues to meet minimum area requirements for background and reflective materials as outlined by the relevant standards.

3. Professional and Clear: Any added text or logos should be professional and easy to read. This is important not only for beauty but also to ensure that the wearer can be easily identified if needed.

4. Durability: Consider the durability of any additions. For example, printed elements should be designed to withstand the wear and tear of a typical work environment without peeling or fading.
