Capacity
The total volume of the suitcase in liters. On the one hand, the number of things that can be placed inside depends on this parameter, and on the other hand, the dimensions and weight of the suitcase itself. The optimal balance between these characteristics depends on the number of people for which the product is designed, as well as on the characteristics of the planned trips.
Conventionally, suitcases can be divided into 3 categories:
small(up to 30 L),
medium(up to 70 L),
large(up to 100 L) and
huge(over 100 L). The first option is well suited for those who are going to travel alone, and the duration of trips is not very long. Also in this category are
children's suitcases, which are distinguished by a catchy design, compact size and special appearance. Medium models are suitable for two people (or, again, for one — with a long journey). And the largest suitcases can be called "family".
Also note that some models may have adjustable dimensions and, accordingly, adjust to the volume; for such suitcases, the maximum volume is indicated in the characteristics — in a fully unfolded state.
Capacity change
The ability to increase / decrease the volume of the suitcase. It is mainly provided by unzipping the zipper around the perimeter of the suitcase. Thanks to
the function of changing the volume, the capacity can be increased, and if not needed, reduced.
Weight
The weight of the empty suitcase. The lower this value, the easier it will be to transport luggage (with the same weight of things placed inside). On the other hand,
lightweight suitcases usually have a less dense body material. Therefore, it is worth choosing a model by weight, taking into account what balance between strength and lightness will be optimal for you.
Number of internal pockets
Internal pockets allow you to sort small things from the general luggage. Mostly made with mesh, which additionally allows you to see what is in your pocket and quickly get access to the necessary "little things".
Material
—
Fabric. Most often, in suitcases, this term refers to various synthetic materials, in particular nylon or polyester. Depending on the density (see below), the properties of the fabric can vary significantly — from a soft, easily crushed shell that provides virtually no protection from impacts to a dense and thick “armor” comparable in protection to thin plastic (although for particularly fragile items, it is still better to use products made of hard materials). In any case, the fabric is quite inexpensive, often has a waterproof coating, and sometimes other special “features” — for example, the Rip-Stop system, which prevents the hole from getting bigger in the event of a rupture. It is also much easier to provide additional pockets (especially external ones) in the design of such suitcases than in
plastic(
ABS plastic,
polycarbonate,
polypropylene) or
metal ones. Due to this, the fabric has become widespread.
— Plastic. Plastic is lightweight and inexpensive; however, due to its hardness, it protects fragile contents from various impacts and loads much better than fabric. However, the strength of this material can vary — there are many types of plastic that differ in characteristics and, accordingly, price. So, ABS plastic is hard due to its heavy weight, but u
...nreliable. It can crack under a strong impact and is unsuitable for subzero temperatures. Emptiness when filled is critical and can lead to deformation under load. But ABS plastic is the cheapest and brightest (any colors and patterns are available). Polycarbonate is resistant to ultraviolet radiation, has increased strength, impact resistance and heat resistance. It is a kind of middle link among plastic models. And polypropylene, which rises above other types of plastic due to its resistance to mechanical damage. It is practically not subject to corrosion cracking, impact resistant. And its flexibility allows it to be used not fully loaded and even empty. After all, if polypropylene bends under the weight of another suitcase, it will restore its shape on its own.
— Metal. Metal gives the suitcase a solid appearance, while it combines hardness with high strength, significantly surpassing plastic in both of these characteristics — metal suitcases are considered the most protected. At the same time, the cost of this material is quite high, the weight is also significant, and the mentioned level of protection is not always required — for most travelers, the capabilities provided by lighter and cheaper plastic products are enough. In this regard, this option has not become widespread.
— Leather. Genuine leather can be considered a premium material. It provides a rich and “presentable” appearance, and costs accordingly — so owning a leather suitcase quite clearly confirms the owner’s status. On the other hand, such models are quite heavy and require quite a lot of care — otherwise, all respectability will be hidden behind cracks and scuffs. So, from a practical point of view, leather is noticeably inferior to fabric and plastic.
