The main purpose of a reflective bag is to increase visibility and reduce the risk of accidents or collisions. The reflective materials on the bag reflect light back to its source, making the wearer or carrier more noticeable in the dark. This is especially important on roads or in areas with limited lighting, where visibility is crucial for personal safety.

Reflective bags are popular among individuals who engage in outdoor activities or commute during darker hours. They are commonly used by cyclists and runners who want to be visible to drivers and other road users. Pedestrians, including students or professionals walking at night, may also opt for reflective bags to enhance their safety.
