A fanny pack is a small, lightweight bag worn around the waist, typically secured with an adjustable strap. It is designed to hold personal items like keys, wallets, and phones, making it a convenient accessory for hands-free carrying. Fanny packs are often made from durable materials and come in various colors and styles. Originally popular in the 1980s and 1990s, fanny packs have made a comeback in recent years as a trendy fashion item. They can be worn in different ways, including around the waist or across the chest, appealing to both practicality and style for various activities like hiking, traveling, or festivals.
