Safety vests, or high-visibility vests, are garments designed to improve the wearer's visibility, particularly in hazardous environments or low-light conditions. They are often worn by construction workers, road maintenance crews, law enforcement officers, and emergency responders, as well as by cyclists, runners, and motorcyclists who need to be visible to others.

Key features of safety vests include:

High-visibility colors: Safety vests are typically made in bright colors such as fluorescent yellow, orange, or green, which stand out against most backgrounds and are easily visible during the day.

Many safety vests feature reflective strips or tape made from PRM, enhancing visibility in low-light conditions by reflecting light to its source, such as vehicle headlights.

ANSI/ISEA compliance: In many countries, safety vests are subject to standards set by organizations like the American National Standards Institute (ANSI) and the International Safety Equipment Association (ISEA). These standards specify requirements for factors such as color, reflective material, and performance criteria to ensure the effectiveness of the vests in enhancing visibility and safety.

Adjustable fit: Safety vests often come with adjustable straps or closures to ensure a comfortable and secure fit for the wearer, allowing them to be worn over clothing or other gear.

Pockets and features: Depending on the specific use case, safety vests may include pockets for holding tools or equipment and features like ID holders or radio loops for added functionality.
