Lightweight luggage is an essential component for an enjoyable, carefree travel experience. Even if bags have wheels and a telescoping handle, they still need to be hoisted up and down at various points during any trip, including an encounter with a flight of stairs, placing items into an overhead compartment or during inclement weather conditions. Therefore, pieces needs to be light enough that they do not place extraneous strain the back, arms or any part of the body. Another reason to carry lightweight luggage is because of the weight restrictions on bags imposed by airlines. Lightweight luggage is generally made from aluminum, polycarbonate, carbon fiber and lightweight fabric materials. Additional features, like high density foam, will help maintain the shape and structure of the bag, while keeping the weight low. Superior components and materials often translate into a higher cost. However, the extra benefits are a worthwhile investment in quality.
