The outside material of luggage can be roughly divided into two types: hard shell and soft shell. These two kinds of suitcases are very different in appearance and characteristics.

The surface of the hard shell luggage is made of hard plastic or carbon fiber, which has good strength and waterproof, solid locking function and more guarantee on security.

Soft shell suitcases are generally made of soft cloth, which is characterized by light weight and relatively cheap. Because the material of the cloth is extendable, it has flexible storage compared with the hard shell. It is suitable for carrying things with thicker luggage.
