Why use a messenger bag instead of a backpack? Unlike backpack straps that can be too small and cumbersome to place on the shoulders and then remove, the messengers are carried by one strap for over the shoulder or cross body. Students and commuters use these because they're designed with a fold over flap and secured by a snap or buckle allowing the main compartment to be easily accessible. They are often referred to as "shoulder book bags" or "courier bags." Many of our messenger bags can accommodate laptops, tablets, MP3 players with an earphone port, business cards and pens, and more. There is usually one main compartment, although some are constructed with additional sections for separating mobile devices and documents. The types of material will range from clear vinyl, polyester to nylon. At Get A Bag we selected a range of various sizes, styles and colors, so selecting one that best fits your lifestyle will be effortless. If you're the student or a professional and need a bag that is versatile, the messenger style bag should be the perfect compliment to your busiest days. If security is an issue at the workplace or campus the clear messenger bag will get you through secure locations quickly and easily.
