School backpacks with bottle compartment

 

— special pockets for bottles are usually located on the sides of the product. They differ from the usual side pockets (see the relevant paragraph) in materials — usually this mesh is combined with an elastic band that can be easily stretched. Thanks to this, you can comfortably carry bottles inside, as well as umbrellas, small tubes and other objects of a similar shape. In some models, the same pocket is regularly used for a pencil case (see "Packaging"), although nothing prevents you from carrying other things. The capacity is usually enough to fit a standard plastic bottle up to 1 liter in a pocket, and in some models up to 1.5 and even up to 2 liters. At the same time, the location and design allow you to get the bottle without even removing the entire backpack (although you still have to do this to return it to your pocket).
