If you go for semi soft sided luggage sets, it is possible to get more storage space. They are prepared with plastic and molded materials. There will not be any internal framework in soft-sided suitcases. They are light in weight and can be expanded very easily. If you go for business cases, laptops and important documents can be stored in a safe way. By going for duffle bags, you will be able to carry more clothes and accessories. For casual travelling, you can consider backpacks. The advantage with backpacks is that they will have shoulder straps so that carrying is made easy.
