Abstract: A light weight, high visibility garment is intended to be worn over regular or service clothing. This garment comprises: a front panel and a back panel that extend from the neck to the hips or waist; mating fastener arrangements at the shoulders and hips detachably connecting the front and back panels; and front and rear retro-reflective bands spanning the front and the back panels. Preferably, the mating fastener arrangements at each of the shoulders include a front arrangement that is affixed to the upper edge of the front panel and a rear arrangement that is affixed to an upper edge of the back panel. When one or both of the panels are grasped and pulled, the mating fastener arrangements separate, thereby freeing the front and back panels from each other and from the wearers body.
