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 external pockets
The presence of pockets in the suitcase allows you to sort small things so as not to search all over the suitcase. External pockets allow you to provide quick access to them. Among those, there can be both small ones for keys, passports, and larger ones where you can put documents, change of clothes.
Fabric density
The density of the fabric from which the suitcase is made (see "Case Material"). This parameter is measured in den; 1 den corresponds to such a density at which a thread 9 km long will weigh 1 gram. Accordingly, the higher the density of the fabric — the thicker the threads used for weaving it, the coarser, tougher it is and the higher the degree of protection (although the weight increases accordingly). The minimum value for modern products is 300 den; 420 den can be compared with the material of ordinary "sports and travel" bags, and in the most advanced models this figure can exceed 1000 den.
Side handle
The presence
of a side handle on the suitcase, which allows you to carry it not in a vertical, but in a horizontal position. This solution appropriately facilitates the transportation of the suitcase, for example, on stairs, on uneven roads (earth, gravel, sand), etc.
