Waist bags, also known as fanny packs, are small, portable bags designed to be worn around the waist. They typically feature an adjustable strap that allows the user to secure the bag comfortably. Waist bags are popular for their convenience, as they keep essentials like keys, wallets, and phones easily accessible while allowing for hands-free movement. These bags come in various styles, materials, and sizes, catering to different activities such as hiking, traveling, or casual outings. Many waist bags are designed with multiple compartments for organization and can be worn in different ways, including across the body or around the hips, making them versatile accessories for everyday use.
