Tote bags are a carry-on piece of luggage that serves a multitude of purposes for men, women and children of all ages. This type of bag is useful for travelers that have a lot of miscellaneous items that they want to keep with them at all times, and within easy reach, such as plane tickets, identification, medical information and prescriptions, lip balm, snacks, water, headphones, sunglasses, eyeglasses, reading material, a hat, scarf or even a light blanket. The all-purpose tote bag is generally lightweight, yet durable and roomy. Multiple interior and exterior compartments will keep contents organized, while zippers, snaps and Velcro closures provide both security and quick access. Popular fabrics include leather, canvas, cotton, nylon and suede. Women may opt for a more feminine version that resembles an over-sized purse, while men often select a structured bag that looks like a briefcase. Many tote bags can also function as a piece of luggage and have wheels and a retractable handle.
