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, appealing to both fashion and practicality. They can be worn in different ways, including around the waist or across the chest, and are favored for outdoor activities, travel, and casual outings.
