Halo is a compact safe shield kit for PM(Personal Mobility) users. Recently, the use of personal mobility has increased, making it an important issue to keep ourselves safe when moving. Brand Halo reinterpreted individual protective equipment as a daily fashion items, so that users can easily use it in their daily lives. Inspired by the form of traffic safety signs, we added safety sign lighting to the X-shaped protector storage bag, which tells users where they are even in the dark of night.
