Designing a protective bag collection needs to be produced with three things in mind – conveyance, organization and co-ordination. Begin with a super durable fashion fabric for the exterior so that the bag will take you through your travels and beyond. It should be spacious and the perfect size for urban commutes and easy air travel. Remember some airlines have weight and size restrictions for carry-on baggage. Leather, suede, vinyls, waxed canvas are ideal choices as they are rugged and durable.
