The laptop matrix, as you know, is measured ininches, so you need to choose a bag based on this. Despite the fact that laptop bags are usually designed for the entire range of modern laptops with the same matrix, the dimensions and sizes can vary greatly depending on the manufacturer, so even a special bag for a 15-inch laptop may not fit models one inch smaller. The computer should be located in the protective structure freely, but at the same time, in no case dangle. That is why the size and dimensions of the bag should be as universal as possible. Some manufacturing companies make their products with the ability to change the size of the case. For example, a modern TOA bag is designed to carry average laptops with a 15.5-inch monitor in diameter, has a main volume of 39x28x10 cm and a total volume of about 17 liters, while this design weighs less than one and a half kilograms, which is almost the smallest possible weight. Bags less than one kilogram in principle do not exist on the market, since the weight directly depends on all the protection provided to your laptop. The main compartment of the popular Kiwidition bag is equipped with special aromatizing inserts made of foam, but non-porous material, which ultimately significantly increases protection from strong mechanical impact. A rigid removable panel allows for quick installation of removable elements inside the structure. Attractive appearance, style, design and advanced protection parameters ultimately allow active use in almost any conditions. Also note that you should not take a universal protective design for all types of equipment, since the specifics of using a particular copy or model greatly affects the requirements for a protective case. For example, it protects much worse if you put a laptop in it and vice versa. But you can carry mobile phones or communicators in such protective bags.
