The sound of the audio begins with the soft rustling of fabric, indicating the wearer adjusting a coat. The coat sounds thick and heavy, suggesting it may be designed for colder weather. Then, there's a distinctive click as the base of the zipper meets its counterpart, marking the start of the zipping process. The subsequent sound is a continuous, rhythmic metallic slide, the unmistakable sound of a zipper being fastened. The zip travels upwards, the sound growing fainter as it moves away from the source. It concludes with a light, satisfying click, signifying the secure fastening of the coat. The rustling of the coat resumes briefly, perhaps the wearer adjusting the fit before venturing out.
