EVA Luggage

Material composition
The trolley case sets are manufactured with varying materials. Hard shell cases are made from polycarbonate, ABS, or polypropylene. These materials are renowned for their strength and flexibility. Softshell bags are made from nylon or polyester fabrics. These prove lighter but stronger than steel and easier to fold and store. The material used in manufacturing a given case directly affects its weight, strength, and, therefore, water resistance.

Dimensions
Whether in pack or unpacked situations, the dimensions of any given trolley bag set are very important. These measurements greatly affect the ease of travel. Most airlines specify allowed luggage sizes. EVA trolley bag sets, therefore, come in various sizes from large down to small to fit standard carry-on and checked bag dimensions. When selecting a bag, check those dimensions to ensure they meet travel requirements where the bag will be primarily used.

Weight
Travel bags weigh quite differently. Carton bags tend to weigh more than their fabric counterparts, while they provide more protection to their contents (hard cases). The total weight of the set, which includes the trolley case, should be minimal, with the added luggage not exceeding the airline restrictions for that specific category. This means that the easier the movement is, the less transport fatigue a traveler will have to deal with.

Closure mechanisms
These Trolley travel case sets are snuggly shut, either with zippers or zipperless closure styles. Zipper closures generally take the form of zippers and sliders. These are securable by locks, usually located at a point of central zip. Fetching items from such cases is easy yet secure. Zipperless cases use latches or snap locks. They provide access without the hassle of zipping and unzipping. The right closure mechanism should provide ease of access yet be secure to prevent loss of items.

Handles and wheels
The conveyance of these trolley sets have been fitted with handles. Also, most have two or four wheels for convenience. The two-wheeled models are generally referred to as a "upright" because they have to be tilted to transport them. The four-wheeled models have wheels that can move in every direction without having to lift the bag off the ground. Another characteristic of this category is that the wheels are often encased in retractable shock absorbers, helping in smooth travel.
