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.
Dimensions (HxWxD)
Dimensions of the suitcase in height, width and depth (it is assumed that the product stands vertically on wheels). For products with volume adjustment, the unfolded dimensions are usually indicated.
It is worth noting that with the same volume, different models may have different sizes; knowing these numbers, you can to some extent evaluate the features of the suitcase and choose the necessary
model of hand luggage on the plane. For example, a large width provides stability when transported on wheels, but is not very convenient when transported on a train — the suitcase may not “fit” under the shelf on the side; wide bags (see "Type") are also less convenient to carry by the handle on the front side, etc.
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".
Laptop compartment
The presence in the design of the suitcase of a special
compartment for a laptop. Using this feature is usually more convenient and safer than carrying a laptop along with the rest of your luggage: such compartments are usually equipped with special straps for fixing, their own reinforced frame, additional soft tabs and other means to protect a valuable item. One has only to take into account that the size of the compartments can be different, and a large laptop (for example, 17 ") may not fit in the selected suitcase model. Therefore, when choosing, you should pay attention to compatible laptop sizes; data on this (usually the largest size of the transported device) usually spelled out in the detailed specifications.
TSA lock
Compliance of the lock installed in the suitcase (see above) with the TSA standard. TSA is an acronym for Transportation Security Administration, i.e. United States Transportation Safety Administration; it was at the suggestion of this structure that similar castles appeared — after the September 11 attacks. These events led to increased security measures during customs inspection, including more frequent opening of luggage — but without an owner with a key, the lock often had to be broken, rendering the product unusable and causing indignation of passengers.
To remedy the situation,
TSA locks were developed. They may differ in design and appearance, be built-in, mounted, etc.; however, all options have two ways of opening and closing — normal and service. The usual one involves the use of a digital code — this is how the owner of the suitcase works with the lock. To open the "service" way, a special key is used that is compatible with all TSA locks; only customs and security officials have such keys. Thanks to this, if necessary, experts can easily and quickly open the suitcase for inspection, and then return it to the owner with a closed and fully functional lock. Some models of locks have an indicator that indicates that it was opened with a service key.
TSA keys are currently used by US, Canadian, UK, and Israeli Customs. So suitcases with such locks are definitely recommended for traveling to these countries; in ad
...dition, the list can expand, so before traveling it makes sense to clarify the features of customs inspection at the destination. Do not neglect this nuance: if they decide to inspect your luggage at the entrance, this will be done anyway, and it depends only on the type of lock whether it will be opened with a service key or brute-forced without the possibility of repair.
