Expandable Luggage: The

Have you ever watched the movie "Transformers"? You must be amazed to see machines transforming from compact items like a car or a motorbike into larger walking robots.

I. What is the secret of an expandable luggage?

Ideal for your extended and international trips, expandable luggage can be expanded to larger ones for heavier load capacity and large storage capacity. The secret lies in the expandable compartments. Judged form the appearance, there are no distinctions between a piece of expandable luggage and an ordinary one, but if you unfold or expand the compartments, they will instantly grow bigger, usually three or more inches to provide even more packing space.

II. How to choose the best expandable luggage?

1. Easy to expand out

The best expandable luggage should be easy to expand. Check if it is easy for you to unfold them. The zippers should be tight and smooth to withstand a high pressure. You can use your fingers to press against the zipped zipper to see if it still remains zipped. The worst zippers are always easy to loose and they may cause a lot of trouble. For example, if the zipper is broken, you cannot either expand the compartments out or fold them back. Twist the case slightly to make sure that it does not wobble from side to side. Try many times and see if it still stays in its shape. If it is, this bag is the right one you need. The lids of best luggage should be stay locked in the open position.

2. Easy to fold back

After you have expanded all the compartments, fill them full with accessible items that you can get from the salesperson. Then take all the packed items out and try to fold the compartments back. At this time, you can try the zippers again and make sure they can be folded back into the case.

3. Materials

Denier is a technical term to measure the size of a fiber in the textile field. In normal condition, smaller denier, polyester luggage is stronger than that with larger denier. Ballistic nylon materials are better than other materials in terms of waterproof and dustproof. A water-resistant fabric is a better choice, because your bag may go through water and stretches in your journey.

Leather expendable luggage is very durable through road tests, although it will show scratches and stains after many trips. If you are looking for endurable luggage that can withstand after years of usage, leather luggage is your choice.

4. Wheels (if they have one set)

Quality wheels are manufactured with a well-made system to maintain luggage's mobility on trips. The internally mounted design can effectively reduce the chance of damage. A large-wheel-base design can keep your luggage from turning over. And a sealed ball bearing design can keep dirt and dust away from wheels. Those having no sealing system may end up with friction in the bearings and eventual wearing-out. No matter what materials the wheels are made of, it is best to choose the smoother and tougher ones with corner wheel designs.

5. Frame

Honeycomb and polycarbonate frames are good at resisting pressures from outside. For most the airlines, they prefer luggage with honeycomb technology, which allows for air "pockets" to make for the lighter weight quality. Fiberglass inner luggage frames offer a lighter load and durability.

6. Warranties

Choose the luggage that is backed up with the longer and complete manufacturer's warranties, if you don't want your expandable luggage become permanently "expanded" or completely frayed, slashed, or wheel-less after couple of trips. A reputable manufacturer and merchant can have your luggage replaced or repaired within the guidelines and duration of the warranty.
