Travel duffels are long, rectangular pieces of luggage that provide generous storage capabilities for everything from shoes and socks, to jackets and sweaters. The large, main compartment, which opens wide via a u-shaped or center zipper, is ideal for rolling up and stacking clothing, to ensure it remains wrinkle-free. Some models have compression buckles, which aid in keeping contents secure. Exterior pockets offer quick, uncomplicated access to smaller items like a compass, GPS system or cell phone. Top and side grab handles come in handy for loading and unloading bags into a trunk or overhead compartment. An adjustable, padded shoulder strap and backpack style straps offer hands-free carrying options, while wheels and a retractable handle make moving heavy loads effortless. Heavy duty fabrics including polyester, canvas, leather and nylon ensure that possessions remain safe from the elements, as well as punctures and abrasions. Travel duffels can be found in various sizes and a plethora of colors combinations and patterns.
