What Do These Terms Really Mean in the Reflective Safety Industry?

In the reflective safety and personal protective equipment (PPE) industry, the terms High Visibility, Hi-Vis, and Hi-Viz are often used to describe the same type of products.
However, these expressions are not interchangeable in professional communication.

Understanding the difference between these terms is important for buyers, brands, and manufacturers—especially in international trade—because terminology affects clarity, credibility, and perceived expertise.

Definition: What Is “High Visibility”?

High Visibility is the full and formal term used to describe clothing, accessories, or equipment designed to make the wearer more noticeable in low-light, dark, or high-risk environments.

It is the most precise and universally accepted expression in the safety industry.

High Visibility is typically used in:

• Technical specifications

• Product manuals

• Safety documentation

• Compliance-related communication

• Formal quotations and contracts

What Does “Hi-Vis” Mean?

It is widely accepted in:

• Marketing materials

• Industry discussions

• Website navigation and SEO content

Hi-Vis maintains a professional tone while offering a shorter, more readable format.
For this reason, it is commonly used by manufacturers, brands, and distributors in commercial communication.

Example uses:

What Is “Hi-Viz” or “Hi Viz”?

Hi-Viz (or hi viz) is an informal spelling variation mainly associated with British and Australasian English.

It is commonly found in:

While hi-viz is easily understood in certain regions, it is not a standardized or professional industry term.

In formal international trade—especially with European mainland markets—using hi-viz in written documentation may appear overly casual or imprecise.

Which Term Should You Use?
